Count Up Timer

Track how much time has elapsed since any date and time — for a project, event, work session, or anniversary.

About this tool

You choose a start date, time, and timezone (or a quick preset). The tool resolves that moment to an exact timestamp and continuously computes elapsed = now − start, so it can't drift regardless of tab throttling or a sleeping device.

How to use it

  1. Pick a start date, time, and timezone, or use a quick-start preset.
  2. Press Start to begin tracking elapsed time.
  3. Use Pause/Resume, Restart, Edit start, or Reset as needed.
  4. Tick "Remember this timer in this browser" to be offered a restore choice next time you open this page.

Example use cases

  • Project duration since kickoff
  • How long a live event has been running
  • Work session / focus session tracking
  • Experiment or test duration
  • Time since a relationship, product launch, or other anniversary

FAQ

What can I use a count up timer for?

Tracking a project's duration, how long an event has been running, a work session, an experiment, or time since an anniversary or milestone — anything measured as "time since X" rather than "time until X".

Does it stay accurate if my laptop sleeps or the tab is inactive?

Yes. Elapsed time is always computed as the current timestamp minus the start timestamp, not by counting up a number on a timer — so whenever you look back, the value is exactly right regardless of what happened while you weren't looking.

Where is my saved timer stored?

Only in this browser's local storage, and only if you tick "Remember this timer in this browser". Nothing is sent to a server. On your next visit you'll be asked whether to restore it or start a new one.
