Unix timestamp (epoch) converter
Convert Unix timestamps in seconds or milliseconds to local date and time, UTC and ISO 8601, and dates back to timestamps. Live epoch clock included.
Timestamp → date
Date → timestamp
How it works
Paste a timestamp and the tool detects whether it is in seconds or milliseconds and shows the date in your time zone, in UTC, in ISO 8601 and how long ago (or until) it is. The other way around, pick a date and time and get its timestamp.
At the top you see the current timestamp updating every second, ready to copy.
