How it works
- 1
Paste a timestamp or a date
1760700000, 1760700000000, 2026-10-17T12:00:00Z or Sat, 17 Oct 2026 12:00:00 GMT all work. The unit is detected from the number’s size.
- 2
Read every format at once
UTC and local time, ISO 8601, RFC 2822, relative time, the weekday, ISO week and day of the year, plus the timestamp in every unit.
- 3
Pick a time zone or copy
Show the date in any time zone. Each value has a copy button; the live clock at the top gives the current timestamp.
Questions
- What is a Unix timestamp?
- The number of seconds since 1 January 1970 00:00:00 UTC (the Unix epoch), ignoring leap seconds. It is the same everywhere in the world, which is why systems store time this way.
- Seconds or milliseconds?
- Unix tools and most APIs use seconds (10 digits today); JavaScript’s Date.now() and Java use milliseconds (13 digits). Microseconds (16) and nanoseconds (19) appear in databases and tracing. The converter detects which one you pasted.
- What is the year 2038 problem?
- Systems that store seconds in a signed 32-bit integer overflow on 19 January 2038 at 03:14:07 UTC (timestamp 2147483647). 64-bit timestamps, used here, run for billions of years.
- Is anything sent to a server?
- No. All conversion uses your browser’s own clock and time zone data.
