Your life, counted in days

Years blur together; days are concrete. The day counter above shows exactly how many times the sun has risen on your life since your date of birth — the total updates against your local date, leap years included.

For context, the cards alongside show your days alive in the other units people ask for: hours, weeks and months. A 10,000-day or 20,000-day milestone is a genuinely fun anniversary — the age line tells you how close you are.

How the day count is computed

The count is the number of whole calendar days between your birth date and today in your local timezone — not an estimate from multiplying years by 365.25. That is why the number matches what you would get by counting every real day on a calendar, including every 29 February you have lived through.

Frequently asked questions

＋How many days old am I?

Select your date of birth and the big number above is your exact day count. It includes every leap day you have lived through and is computed against your local date.

＋When do I turn 10,000 days old?

Add 10,000 to your "total days alive" starting point: your 10,000th day is 10,000 days after your birth date. The same arithmetic works for 20,000 or any milestone you like.

＋Do leap years affect my age in days?

Yes, and they are fully accounted for. The count uses real calendar days, so every 29 February you have lived through adds one day compared to a 365-day approximation.
