Oregon Parenting Time Calculator

Oregon calculates parenting time by counting the average number of overnights each parent has with the child over a two-year period under OAR 137-050-0730. The total overnights are divided by 365 to determine the parenting time percentage. If parents have an alternative schedule where significant time occurs without overnights, 12 continuous hours may count as one overnight. The Oregon Department of Justice offers an official Parenting Time Calculator to help parents determine these percentages.

In Oregon, a parent must have at least 73 overnights per year (approximately 20% of parenting time) to receive parenting time credit in child support calculations under OAR 137-050-0730. This threshold triggers adjustments to the child support obligation. True 50/50 shared custody occurs at 182.5 overnights annually, which results in equal parenting time credit for both parents. Split custody, where each parent has primary custody of different children, requires each parent to have a child more than 50% of the time.

A 2-2-3 custody schedule in Oregon rotates children between parents every 2, 2, and 3 days, creating a 50/50 parenting time split with 182.5 overnights per parent annually. This schedule works well for younger school-age children who benefit from frequent contact with both parents. Oregon courts and the Department of Justice recognize this as a common arrangement. Many parents simplify to week-on/week-off during summer to reduce exchanges while maintaining equal time.

Parenting time directly reduces child support obligations in Oregon through the parenting time credit formula under OAR 137-050-0730. Parents with at least 73 overnights annually receive credit that reduces their support amount. The credit percentage uses a complex formula where lower parenting time yields smaller credits, while equal parenting time (182.5 overnights) results in equal credit. Oregon's Parenting Time Calculator automatically factors these overnights into the child support calculation.

Yes, Oregon allows parenting plan modifications under ORS 107.135, but you must demonstrate a substantial change in circumstances since the last order and prove the modification serves the child's best interests. Repeated and unreasonable denial of parenting time can constitute a substantial change. If parents agree, they can file a stipulated modification. Without agreement, mediation is typically required before trial. Modifications require filing a motion with the court and submitting a new proposed parenting plan.

Oregon's Birth to Three Parenting Guide recommends infants (0-12 months) have frequent 2-4 hour visits two or three times weekly to build secure attachment, rather than overnight stays. For toddlers ages 1-3, overnight stays can gradually increase, but children ideally should not be separated from either parent for more than 4 consecutive days. By ages 3-5, children can handle longer blocks of time with each parent. Oregon courts provide sample schedules with developmentally appropriate options for each age group.

Oregon parenting plans must include a holiday schedule that takes precedence over regular parenting time and summer schedules. Parents typically alternate major holidays annually—Thanksgiving with one parent in odd years and the other in even years. Winter break is commonly split in half at a designated midpoint. The Oregon courts provide Attachment 4.2 in parenting plan forms for listing additional family holidays. Parents can customize provisions, though courts recommend avoiding vague 'as-needed' arrangements.

First right of refusal in Oregon parenting plans means that when a parent needs childcare during their parenting time, they must first offer that time to the other parent before using a babysitter or daycare. Oregon law does not mandate this provision, but parents can include it in detailed parenting plans. Effective clauses specify a minimum absence duration (typically 5-8 hours), required notice period, and response timeframe. Courts may decline to include this provision in cases involving domestic violence history.
