How we calculate these dates
The published table uses the next valid occurrence of May 17, 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 May 17?
- May 17, 2027 is 223 calendar days away in UTC. It falls on Monday.
- Why can the live timer differ from the calendar-day count?
- 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 May 17, 2027?
- Using six calendar months, it is November 17, 2027. If the destination month is shorter, we use its last day. This is a planning convention, not a rule about when to celebrate.
