Pull out your existing custody order or parenting plan firstHoliday schedules usually override the typical parenting plan, so check what it already says before you agree to anything new; changing the plan without putting the new version in writing can cause real problems later.
List every holiday, school break, and special occasion that matters to either householdInclude birthdays, religious holidays, and days that matter to step-relatives, not just the "big" federal holidays.
Start the conversation months ahead, not weeksSeptember and October are ideal months to open the conversation, but even early November gives you enough time to iron out details without last-minute pressure.
Loop in the new spouse or partner before finalizing anythingA blended-family schedule affects their plans (and their own kids' schedules) too, so surprises here cause the most friction.
Talk to the kids about what matters most to themA specific tradition, a person, a place — before you lock in a structure that ignores it.

Choose and write the actual structure

Pick a model for splitting each holiday if choose based on distance and family preferenceIn even-numbered years one parent has the kids for a specific set of holidays and the other has them in odd-numbered years, or, if co-parents live close enough, they can split each holiday into two parts, with children spending the morning with one parent and the evening with the other.
Consider fixing certain holidays to certain households instead of alternating if preferences differ by holidayUseful when one co-parent values Thanksgiving more while the other values the Fourth of July, so each celebrates their preferred holiday every year.
Set a firm handover time and location for each holiday, not just a date"Christmas Day" is ambiguous; "9am at the school parking lot" isn't.
Decide who handles which holiday traditions across both householdsSo kids aren't caught choosing between two competing versions of the same event.
Put the whole thing in writing and get sign-off from both co-parents (and ideally new spouses)Put every agreement in writing, build in flexibility for travel or unexpected changes, and focus on preserving the spirit of the season for your children.
Get a family law attorney to formalize it into your order if your custody arrangement is court-ordered if history of conflict"Any responsible attorney will advise parents the importance of a concrete and specific holiday parenting time plan, even in the best of times... new relationships or changing circumstances can make holiday schedules much less straightforward than co-parents initially anticipated."

Handle travel and logistics

Set a notice deadline for any holiday travel that affects the scheduleMost agreements require written notice at least 30 to 60 days before the planned travel, including dates, destination, and contact information.
Get extra documentation ready if a trip crosses state or national borders if trip crosses state or national bordersIf the child will be out of state or traveling internationally, your agreement may require additional documentation or consent.
Agree in advance on who pays for and arranges transportation between households for each handoverEspecially for longer holiday breaks.
Decide how a family vacation that overlaps a shared holiday gets resolved if vacation overlaps shared holidaySome families agree pre-planned vacations may override holidays; write down your family's rule now, not in the moment.
Coordinate gift-giving so kids aren't caught between competing or duplicate presentsA quick check-in avoids two families buying the same big-ticket item.

Share it and keep it working

Send the finalized schedule to everyone who needs itBoth households, new partners, and any grandparents or relatives hosting a gathering.
Put dates on a shared calendar or co-parenting appSo nobody is relying on memory for handover times months out.
Confirm each holiday's plan again a week or two beforehandEssential for anything involving flights or non-refundable bookings, since plans can shift.
Build in an agreed process for swaps or tradesSo a one-off change (a family reunion, a sick day) doesn't require renegotiating the whole plan.
Revisit the schedule every year or two as kids grow if kids develop own preferencesEspecially once kids are old enough to have their own preferences or plans with friends.
Keep the schedule flexible where you can, firm where it countsThe goal is stability for the kids, not a rigid rulebook neither household can actually live with.
