Time since a date

Pick a past date to see how much time has elapsed since then.

How Time since a date works

Time since a date counts up from a past date to now, broken down into years, months and days, plus totals (total days, weeks and so on). Perfect for anniversaries, sobriety streaks, project age or "how long since…" questions.

It is the mirror image of a countdown: where Days until a date and the Countdown timer look forward, this looks back. For the gap between two arbitrary dates (not necessarily today), use Date difference. Because it measures against the current date, reopening the page later shows the updated elapsed time.

Frequently asked questions

How is this different from Date difference?

Time since a date always measures from a past date up to right now and emphasises the running total. Date difference compares any two dates you choose, in both directions, use it when neither end is "today".

Does it keep counting as time passes?

It reflects the moment you open or refresh the page. Because it computes against the current date on your device, reopening it later shows the updated elapsed time.

Is the date I enter sent anywhere?

No. Every value is computed in your browser, on your device. The date you enter never leaves your machine and nothing is stored between visits.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.

Is it free? Do I need an account?

It is completely free and requires no sign-up. There are no watermarks, no daily limits and no tracking cookies needed to use the tool.
