How long until…?

Seasonal quick answer: there are 19 days until Halloween 2026 (Saturday, October 31) as of October 12 — that's about 2 weekends left. The countdown below tracks it to the second, and works for any date.

We count from the very start (midnight) of the birth date you enter, not the exact hour you were born — most people don't have that on hand. Because of that, your days-alive total ticks up by one right at midnight each night. Today counts as a full day only once that midnight has passed; while today is still underway, it isn't included yet.

The four milestones — 10,000 days (about 27 years old), 15,000 (about 41), 20,000 (about 55), and 25,000 (about 68) — are the round day-counts most visitors will actually reach or are approaching. They're popular because they're clean, satisfying round thousands, not because life stops mattering after 25,000 days; we may add higher milestones like 30,000 down the line.

Yes, when you ask for one. Calculating does not change the address bar — your event name and date stay in the tab. Press 'Copy link to this countdown' and the page writes them into the address and copies it, so anyone who opens that link sees the exact same countdown, already running. Until you press it nothing is in the address; afterwards a 'Clear share link' button takes it back out. See the privacy policy.

No — the ticking numbers are plain JavaScript running in your open browser tab, not something scheduled on a server. Close the tab and the countdown stops. Reopen the same link later and it doesn't pick up where it left off; it simply recalculates the correct remaining time from that new moment, so the numbers are always accurate.

Whatever time zone your device is currently set to. The date and time you pick are read as local time on your device, and compared against your device's current local clock. If you share a countdown link with someone in another time zone, they're counting down to the same real-world moment — it'll just display relative to their own clock, not yours.

Christmas 2026 falls on Friday, December 25. Tap the Christmas chip above and the live counter shows the exact days, hours, and minutes remaining — recomputed from your device clock on every visit, so it's current whenever you land here.

Halloween is always October 31 — in 2026 that's Saturday, October 31. Tap the Halloween chip above (or enter any date) and the countdown ticks down live; the date is fixed and the math runs fresh on every visit, so this page never shows a stale day count.
