Epoch to Date Converter
Paste a Unix timestamp and convert it to a readable date in any timezone. The converter detects seconds vs milliseconds and shows ISO 8601, UTC, local date, time, weekday, and relative time.
Convert Unix timestamps to readable dates
Epoch time is compact and reliable for systems, but it is hard to inspect by eye. This page focuses on the timestamp-to-date direction: enter a 10-digit Unix timestamp in seconds or a 13-digit timestamp in milliseconds, choose a timezone, and read the same instant as a normal calendar date.
What the output formats mean
The converter returns several common date formats so you can copy the one your workflow needs.
- ISO 8601 includes the local UTC offset and is the safest format for APIs and logs
- UTC string shows the same instant in Coordinated Universal Time
- Friendly local output is useful for humans checking schedules or debugging events
- Relative time helps confirm whether the timestamp is in the past or future
Seconds vs milliseconds
Most backend languages use Unix seconds, while JavaScript and many browser APIs use milliseconds. The converter detects the unit from the size of the number, which prevents the common mistake of converting a modern timestamp into a date near 1970.
