How it works

Frequently asked questions
- How is the next Summer date chosen?
- When today's UTC date is on or after this year's Summer, the counter automatically targets the following year's occurrence.
- Why does this countdown use UTC?
- Calendar-day counts and the target midnight are based on Coordinated Universal Time (UTC), so results are consistent worldwide. Local time zones may show a different calendar day near midnight.
