Take control of time

MyTempos includes five tools: a countdown timer (set a date, name it, share the link), a date calculator (add or subtract days, weeks, months, or years from any date), an age calculator (exact age in years, months, and days), a working days calculator (count business days between two dates, weekends excluded), and a duration tool (find the exact time between two timestamps).

No. MyTempos works entirely without an account. There is no sign-up, no login, and nothing to install. Your calculations are never stored on our servers — everything is encoded directly in the URL, so you can bookmark or share any result without ever identifying yourself.

Every result has a unique URL that encodes your inputs. Use the "Copy link" button or just copy the address from your browser bar. Anyone who opens the link sees the same result instantly — they don't need an account either. Countdown links stay live and tick in real time for anyone who opens them.

Yes, completely free. No premium tiers, and no limits on how many calculations you run. MyTempos is a free tool, full stop.

Yes. MyTempos is fully responsive and works on any device — phone, tablet, or desktop — in any modern browser. No app to download, no mobile sign-in.

All calculations use your device's local clock and standard calendar arithmetic. Countdowns update every second in real time. Date and duration results are exact to the day. The age calculator is exact to the day of birth. For timezone-sensitive calculations, results reflect your local system timezone.

All calculations are done in your browser. We do not store any of your data.
