Unix timestamp (epoch) converter
A Unix timestamp is the number of seconds since 1 January 1970, 00:00 UTC. Paste one to see the date and time in IST (UTC+5:30) and UTC; the tool detects milliseconds automatically (13 digits). Or pick a date and time to get its timestamp in seconds and milliseconds — for APIs, logs, JWT expiry, database records and cron jobs.
Quick reference
- 1 day = 86,400 seconds; 1 hour = 3,600; 1 week = 604,800.
- Milliseconds to seconds: divide by 1,000 (drop the last three digits).
- Epoch 0 = 1 Jan 1970 05:30 IST. The 32-bit limit (2,147,483,647) is 19 January 2038.
- JavaScript:
Date.now()gives milliseconds; Python:time.time()gives seconds.
