How we calculate these dates
The published table uses the next valid occurrence of June 18, 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 June 18?
- June 18, 2027 is 255 calendar days away in UTC. It falls on Friday.

- When is the half-birthday after June 18, 2027?
- Using six calendar months, it is December 18, 2027. If the destination month is shorter, we use its last day. This is a planning convention, not a rule about when to celebrate.
