Timestamp Converter
Convert between Unix timestamps and human-readable time (seconds/milliseconds).
What is Timestamp Converter
Two-way conversion between Unix epoch timestamps and readable date-times. Paste a stamp and pick seconds (10 digits) or milliseconds (13 digits) to get the date in several formats, or enter a date and time to get the stamp back. The current epoch time ticks live at the top.
How to use Timestamp Converter
- Paste a Unix timestamp and choose seconds or milliseconds
- See the converted date in every format

Frequently asked questions
Seconds or milliseconds?
JavaScript and most APIs use milliseconds since 1970-01-01 UTC; Unix tools and logs usually use seconds. The page labels the 10-digit and 13-digit options explicitly — do not mix them.
What moment does timestamp 0 mean?
The Unix epoch: 1970-01-01 00:00:00 UTC — 08:00 in the UTC+8 zone. Every timestamp counts seconds or milliseconds forward from that instant.
Which timezone does the result use?
Your browser's local timezone (UTC+8 in China). A Unix timestamp itself is timezone-independent — only the rendered date is localized.
