Timestamp Converter help

Read a Unix timestamp or a date string as every common representation. Everything runs in your browser.

Input

• now for the current time.
• A plain number is treated as an epoch: up to 11 digits is seconds, 12–14 is milliseconds, 15+ is microseconds.
• Anything else is parsed as a date string, so 2026-09-08T12:00:00Z works.

Output

Unix seconds / milliseconds / microseconds, ISO 8601, the RFC UTC string, a local string in the time zone you pick, date-only and time-only, the weekday, the ISO week number, and a "3 days ago" style relative phrase. Click any value to copy it.

Notes

• The time-zone list is a short set of common zones; the "Local" row uses whichever you select.
• Relative time is measured against your device clock at the moment you look.
