Alaska Custody
Time Calculator

Calculating parenting time is a critical step in any Alaska custody case. Whether you are negotiating a custody agreement, preparing a proposal for the court, or evaluating a schedule your co-parent has proposed, understanding exactly how many overnights and days each parent receives — and how those numbers translate into percentages — determines both the parenting schedule and, in most cases, the child support obligation.

Alaska does not have a statutory presumption for joint custody — instead, the court applies a best interest of the child analysis (Alaska Stat. § 25.20.060).

Alaska requires a detailed parenting plan in all custody cases and considers domestic violence as a factor that weighs heavily against the perpetrating parent.

Alaska custody proceedings under Alaska Stat. § 25.20.060 require a detailed parenting plan in all cases, addressing physical custody, legal custody, decision-making authority, and dispute resolution.

Alaska's income shares child support model under Alaska R. Civ.

P. 90.3 applies a shared custody calculation when each parent has a substantial number of overnights, and the exact overnight count drives the monthly support figure.

Anchorage (Third Judicial District) handles the majority of Alaska custody cases; geographic distance between parents is a recurring issue in Alaskan parenting plans, often leading to extended summer and holiday blocks rather than alternating weekly schedules. Accurately computing annual overnights with a parenting time calculator is essential before any Alaska parenting plan is filed.

Alaska uses an income shares model for child support (Alaska R. Civ.

P. 90.3), and parenting time percentage directly affects the calculation.

This means the schedule you negotiate is not just about when you see your children — it has a direct dollar-per-month impact on both households' finances. Understanding this connection between time and money is essential for informed negotiation.

This calculator helps you model different parenting schedules — 50/50, 60/40, 70/30, every-other-weekend, and custom arrangements — and see the exact percentage of time each parent receives. You can adjust for holidays, summer vacation, and special schedules to get an accurate annual percentage.

Use it before negotiating, before mediation, and before any court appearance where custody time is at issue.

Alaska does not have a statutory presumption in favor of joint or sole custody (Alaska Stat. § 25.20.060).

Instead, the court evaluates the totality of the circumstances using the best interest of the child standard. This gives judges broad discretion to craft a parenting schedule tailored to the specific family's situation.

Neither parent enters the courtroom with a built-in advantage — the outcome depends entirely on the evidence.

Without a presumption, the parent seeking more time must present compelling evidence of their involvement in the child's life, their ability to provide a stable and nurturing home, and the feasibility of their proposed schedule given the parents' work schedules, geographic proximity, and the child's school and activity commitments. The "friendly parent" factor — which parent is more likely to encourage a healthy relationship between the child and the other parent — can be decisive in Alaska cases where both parents are otherwise equally fit.

The absence of a presumption in Alaska makes preparation critical. Courts consider the status quo — the existing arrangement during the separation period — as evidence of what works.

If one parent has been the primary caretaker during the separation, the court may be reluctant to dramatically change the schedule absent compelling reasons. This means the custody arrangement you establish during the separation period (even informally) can influence the final order.

The best interest factors in Alaska are codified at Alaska Stat. § 25.24.150(c).

These factors are not ranked — the court weighs all of them together. They typically include: the emotional ties and relationship quality between the child and each parent, each parent's capacity to provide food, clothing, medical care, and other material needs, the stability and continuity of the child's current living situation, the child's adjustment to their home, school, and community, the mental and physical health of all parties, each parent's willingness to respect and facilitate the child's relationship with the other parent (the "friendly parent" factor), any history of domestic violence or abuse, and the reasonable preference of the child if the child is of sufficient age and maturity to express a meaningful opinion.

50/50 (equal time — 182.5 overnights per parent per year): The gold standard for shared parenting. Common implementations include: (1) Alternating weeks — the child spends one full week with each parent, switching on a set day (usually Friday or Sunday).

This schedule is simple and provides long uninterrupted stretches with each parent, but the 7-day gap can be difficult for younger children. (2) The 2-2-3 rotation — the child spends 2 days with Parent A, 2 days with Parent B, then 3 days with Parent A, then the pattern reverses the following week.

This means no parent goes more than 3 days without seeing the child, which works well for younger children but involves more transitions. (3) The 3-4-4-3 schedule — 3 days with one parent, 4 with the other, then alternating.

While Alaska does not presume equal time, courts increasingly award 50/50 schedules when both parents are fit and live in close proximity.

60/40 schedule (approximately 219 overnights vs. 146): This arrangement gives one parent primary custody during the school week while the other parent has extended weekends and one midweek evening or overnight.

A common implementation is "every other weekend (Friday to Sunday) plus every Wednesday overnight," which produces roughly 146 overnights for the non-primary parent (40.0%). Another variation is "every other weekend (Friday to Monday) plus alternating Wednesdays," which can push the split closer to 45/55.

The 60/40 arrangement is common in Alaska when one parent has historically been the primary caretaker, when parents live more than 20–30 minutes apart (making school-day transitions impractical), or when one parent's work schedule is incompatible with weekday custody.

70/30 schedule (approximately 256 overnights vs. 109): This is essentially the "every other weekend plus one evening" schedule — the traditional arrangement that was standard in most states before the shared parenting movement gained momentum.

The non-primary parent has the child every other weekend (Friday evening to Sunday evening) and one weekday evening per week (but no overnight). In Alaska, this schedule is now reserved for situations where equal or near-equal time is inappropriate: significant geographic distance between homes, documented domestic violence or substance abuse history, a very young child who has not yet formed a strong attachment to one parent, or a parent's work schedule that includes nights or extensive travel.

Holiday and vacation schedules override the regular rotation. In Alaska, a typical holiday schedule alternates major holidays (Thanksgiving, Christmas/Hanukkah, New Year's, Fourth of July, Memorial Day, Labor Day, Easter/Passover) between parents in odd and even years.

Each parent typically gets 2–4 weeks of uninterrupted summer vacation, scheduled in advance. The holiday schedule is critical because it affects the total annual overnight count — and therefore the parenting time percentage and child support calculation.

A seemingly minor holiday adjustment of 5–10 overnights can shift the annual percentage enough to cross a child support threshold.

Alaska requires a detailed parenting plan in all custody cases. The plan must specify: (1) the regular weekly schedule, (2) holiday and vacation schedules, (3) transportation arrangements for exchanges, (4) decision-making authority (education, healthcare, extracurricular activities, religious upbringing), (5) communication protocols between the parents and between the child and the absent parent, and (6) a dispute resolution mechanism (mediation, parenting coordinator, or return to court).

Courts in Alaska will not finalize a custody order without an approved parenting plan. The more detailed and specific the plan, the less room for conflict later.

Alaska uses an income shares model for child support (Alaska R. Civ.

P. 90.3).

Understanding how this model works — and specifically how parenting time feeds into the calculation — is essential for evaluating any proposed custody schedule. The schedule you agree to is not just about when you see your children; it has a direct, quantifiable impact on both households' monthly budgets.

In the income shares model, both parents' gross incomes are combined to determine the total child support obligation based on a statutory table. This combined obligation is then apportioned between the parents based on each parent's share of the combined income.

For example, if Parent A earns $60,000 and Parent B earns $40,000, Parent A's share of combined income is 60% and Parent B's is 40%. If the table sets the total obligation at $1,200/month, Parent A's proportional share is $720/month and Parent B's is $480/month.

The parent with less parenting time pays their share to the parent with more time.

The parenting time adjustment reduces the payer's obligation when they have the child for a significant portion of the year. The logic is that the parent incurs direct expenses (food, utilities, activities) when the child is in their home.

In most income shares jurisdictions, this adjustment kicks in when the payer has more than approximately 80–92 overnights per year (roughly 22–25% of the time). Above that threshold, the support obligation decreases as parenting time increases.

At exactly 50/50 time, the calculation typically produces a much smaller obligation from the higher-earning parent to the lower-earning parent — or no obligation at all if incomes are roughly equal.

The crossover thresholds matter enormously. In Alaska, moving from a 70/30 schedule (109 overnights) to a 60/40 schedule (146 overnights) can reduce the noncustodial parent's child support by 20–30%.

Moving to a true 50/50 schedule (182.5 overnights) can reduce or eliminate the obligation entirely, depending on the income differential. A difference of just 10–15 overnights per year can cross a threshold that changes child support by hundreds of dollars per month.

This is why accurately calculating parenting time percentages — including holidays and vacation adjustments — matters so much. Use this calculator to model different schedules and see the exact overnight count and percentage before negotiating.

A comprehensive parenting plan is the foundation of any successful custody arrangement in Alaska. Whether you negotiate the plan through mediation, collaborative law, or direct negotiation with your co-parent, the plan should address every foreseeable scheduling scenario to minimize future disputes.

Alaska requires a parenting plan in all custody cases — the court will not enter a final order without one.

The regular schedule is the backbone of the plan. Specify which days and overnights each parent has during a typical two-week cycle, including exact transition times and locations.

"Every other weekend" is too vague — does it start Friday at 6:00 PM, Friday after school, or Saturday morning? Does it end Sunday at 6:00 PM or Monday morning at school drop-off?

These details prevent arguments. For Alaska families, also specify how the schedule adjusts during school breaks, teacher workdays, and snow days.

The more specific the plan, the fewer disputes you will have.

Holiday schedules should alternate major holidays by odd and even years. A typical Alaska holiday rotation covers:

• Thanksgiving — Wednesday before through Sunday.

• Christmas/winter break — split into two halves (Christmas Eve–December 26 and December 26–New Year's Day).

• Spring break, Memorial Day weekend, Fourth of July, and Labor Day weekend.

• Each parent's birthday, Mother's Day, and Father's Day.

Summer vacation is typically split into 2–4 week blocks, with a deadline (often April 1 or May 1) for each parent to designate their preferred weeks. Many Alaska plans also address three-day weekends and school-specific holidays.

Decision-making authority should be clearly allocated. Joint legal custody in Alaska means both parents must agree on major decisions — education (school choice, tutoring, special education services), healthcare (non-emergency medical treatment, therapy, medication), extracurricular activities (sports, music, camps), and religious upbringing.

The plan should specify what happens when parents cannot agree: most Alaska plans designate one parent as the tie-breaker for specific categories (e.g., Parent A decides education, Parent B decides extracurricular activities) or require mediation before returning to court.

Communication protocols are increasingly important in Alaska custody plans. The plan should address four areas:

• Parent-to-parent communication — specify the channel (text, email, or a co-parenting app like OurFamilyWizard or TalkingParents) for scheduling and decisions.

• Child-to-parent communication — the child's right to call or video-chat the absent parent, and at what frequency.

• New romantic partners — rules and notice requirements before introducing a new partner to the child.

• Social media boundaries — what each parent may post about the child without the other's consent.

Some Alaska courts also require a "right of first refusal" clause — if the custodial parent cannot care for the child during their scheduled time, they must offer the time to the other parent before arranging childcare.

The optimal parenting schedule in Alaska changes as the child grows. Developmental psychology research and Alaska court practice both recognize that what works for a toddler is very different from what works for a teenager.

Courts in Alaska frequently order age-appropriate modifications to existing schedules as children develop, which means any custody order should include a mechanism for revisiting the schedule at key developmental milestones.

Infants and toddlers (0–3 years): Young children form primary attachments and need consistent routines. Alaska courts are cautious about extended overnights away from the primary attachment figure for very young children.

A typical schedule for this age might include frequent but shorter visits with the non-primary parent — several 3–4 hour blocks per week, gradually increasing to include one overnight, then two overnights per week as the child approaches age 2–3. The goal is to build the child's comfort and attachment to both parents without disrupting the security of the primary bond.

Preschool and early elementary (3–7 years): Children in this range can handle longer periods away from the primary parent but still benefit from regular transitions (no more than 3–4 days without seeing each parent). The 2-2-3 rotation or 2-2-5-5 schedule works well for this age group.

Alaska courts look at whether the child has successfully adjusted to overnights with both parents and whether both parents can manage the child's daily routines (meals, bedtime, school preparation). By age 5–6, most children can handle a week-on/week-off schedule if both parents are capable.

School age (7–12 years): School-age children can handle longer stretches with each parent (alternating weeks is common), but the schedule must accommodate school attendance, homework, extracurricular activities, and social commitments. The school the child attends often drives the schedule — if both parents live in the same school district, flexibility is easier.

If parents live in different school districts, the child typically attends school from one parent's home, and the other parent has extended weekends and vacation time. Alaska courts consider the child's academic performance and social connections when evaluating the feasibility of proposed schedules for this age group.

Teenagers (13–18 years): Adolescents have their own social lives, activities, part-time jobs, and preferences. Rigid adherence to a custody schedule becomes increasingly impractical.

Alaska courts give greater weight to a teenager's preferences — while no Alaska statute sets a specific age at which a child can "choose," courts generally take the preferences of a 14+ year-old seriously as one significant factor. The practical challenge with teenagers is that they may resist transitions, prefer one home due to proximity to friends or school, or want flexibility that a fixed schedule does not provide.

The most successful plans for teenagers build in structured flexibility — a default schedule with a mechanism for the teen to request modifications with both parents' consent.

After a custody order is entered in Alaska, the court will modify it only upon a showing of a "material change in circumstances" that affects the child's best interest. This is a deliberately high bar — courts value stability and continuity for children and will not revisit custody arrangements simply because a parent is dissatisfied with the outcome or believes they could present a better case the second time around.

The parent seeking the modification bears the burden of proof.

Common material changes that Alaska courts recognize:

• Parental relocation that substantially affects the parenting schedule — most Alaska courts require 30–60 days advance notice before a custodial parent can relocate, and the non-relocating parent can object.

• A significant change in a parent's work schedule that makes the current arrangement impractical.

• The child's developmental needs changing as they age — particularly the transition from preschool to school age or from elementary to middle school.

• Evidence of abuse, neglect, or substance abuse that was not present at the time of the original order.

• A parent's persistent failure to follow the existing custody order (contempt).

• The child's own expressed preferences as they mature, particularly for teenagers.

The modification process in Alaska typically involves four steps:

• File a motion with the family court that issued the original order, with a declaration detailing the specific changed circumstances.

• Mediation — required or strongly encouraged in most Alaska jurisdictions — to attempt resolution before a hearing.

• Discovery and potentially a custody evaluation if the parties cannot reach agreement.

• A hearing before a judge. The full process typically takes 3–12 months. Use this calculator to model the proposed new schedule before your hearing. Reference: Alaska Stat. § 25.20.060; Alaska Stat. § 25.24.150(c).

Enforcement is different from modification. If your co-parent is not following the existing custody order — denying scheduled parenting time, refusing to return the child, or unilaterally changing the schedule — you can file a contempt motion rather than a modification motion.

Contempt does not require showing a material change in circumstances; it requires only showing that the other parent willfully violated a court order. Alaska courts can impose sanctions including make-up parenting time, attorney fee awards, fines, and in extreme cases, incarceration.

Document every violation with contemporaneous written records (texts, emails, dated notes).

The connection between custody time and child support makes accurate schedule modeling essential. Even seemingly small schedule changes — adding one midweek overnight, extending holiday time by a few days, adjusting summer vacation blocks — can shift the annual parenting time percentage enough to cross a child support threshold.
