About the Timestamp Converter
This Unix timestamp converter translates between epoch timestamps and human-readable dates. A Unix timestamp is the number of seconds (or milliseconds) since January 1, 1970 UTC — a compact, timezone-independent way to store a moment in time that is used throughout programming and databases.
Paste a timestamp in seconds or milliseconds (the tool auto-detects which) or a date string, and see the local time, UTC, ISO 8601, and both epoch formats side by side. A live clock shows the current timestamp so you always have "now" at hand.
How to use it
- 1Read the current Unix time from the live clock at the top, or click Use now.
- 2Enter a Unix timestamp (seconds or milliseconds) or a date like 2026-01-01.
- 3View the converted local time, UTC, ISO 8601, and epoch values.
- 4Copy whichever format you need.
Common use cases
- Converting database timestamps to readable dates
- Debugging time-based bugs across timezones
- Generating the current epoch time for testing
- Translating log timestamps
Frequently asked questions
Does the tool use seconds or milliseconds?
It auto-detects: a 10-digit number is treated as seconds and a 13-digit number as milliseconds. The output shows both, so you can copy whichever your system expects.
What is ISO 8601 format?
ISO 8601 is an international date-time standard like 2026-01-01T00:00:00.000Z. It is unambiguous and sorts correctly as text, which makes it a common choice for APIs and logs.
What timezone are the results in?
Local time uses your device’s timezone, while UTC and ISO 8601 are shown in Coordinated Universal Time. The Unix timestamp itself is timezone-independent.
