How we calculate these dates
The published table uses the next valid occurrence of December 10, including today when it matches. We subtract whole calendar days in UTC for the checklist, so a daylight saving clock change does not move a planning date. The live timer uses local midnight and updates while this tab is visible. Neither calculation includes travel time or venue opening hours.

Quick answers
- How many days until December 10?
- December 10, 2026 is 65 calendar days away in UTC. It falls on Thursday.

- The table counts calendar dates using UTC and refreshes hourly. The timer counts complete 24-hour periods, hours and minutes until local midnight on your device. Time zones and daylight saving changes can make the two counts differ.
- When is the half-birthday after December 10, 2026?
- Using six calendar months, it is June 10, 2027. If the destination month is shorter, we use its last day. This is a planning convention, not a rule about when to celebrate.
