Days Since Date

Day counter

Count the days since or until any date. Name it, and the page gives you a link you can save or share that reopens the same count.

Counted in whole days – the total rolls over at midnight in your own timezone, and leap days are counted exactly. Nothing you enter leaves your browser; the link is built in the page.

Counting forwards and backwards

A past date gives days since, a future date gives days until, and the counter switches between the two on its own. Both use the same arithmetic: the number of complete days between two calendar dates, with every leap day in the period included. That is why a ten year span comes to 3,652 or 3,653 days rather than 3,650.

Milestones

Once a date is set, the table below fills with the round day numbers people tend to mark: 100, 500, 1,000 and so on, each with its calendar date, weekday and distance from today. Those are the numbers worth putting in a calendar, because unlike anniversaries they never land on the same date twice and are easy to miss.

Saving a count

Nothing is stored on a server, so a count lives in its link. Set a date and a label and the box above fills with a URL containing both. Bookmark it and the page reopens on the same count, recalculated for whatever day you open it. Nothing about the count is recorded here and there is no account to make.

Questions

How many days since a date?
Enter the date above. The counter gives the exact number of complete days, plus weeks, months and hours.
Does it count the start date itself?
No. The start date is day zero and the following day is day one, which is the same convention as an age or an anniversary.
Can I count to a future date?
Yes. Pick any date up to 2030 and it counts down instead of up.
Is my date stored anywhere?
No. The calculation runs in your browser and the shareable link is built there too. Nothing is sent to us.
