How long until…?
Pick any moment and watch the countdown tick live, or enter your birthdate to see how many days you've been alive — and when your next big day-count milestone lands.
Frequently asked questions
How is 'days alive' calculated — does it count today?
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.
Why do the milestone numbers stop at 25,000 days?
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.
Can I share a link to a specific countdown?
Yes. As soon as you hit Calculate (or tap a preset chip), the page rewrites its own address bar to include your event name and date as link parameters — nothing is ever sent to a server. Copy that URL, or use the 'Copy link to this countdown' button, and anyone who opens it will see the exact same countdown, already running.
Does the countdown keep running if I close the tab?
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.
What time zone does this use?
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.
