Frequently asked questions

What is UTC?

UTC (Coordinated Universal Time) is the world's primary time standard. It does not observe Daylight Saving Time and is the reference point for all other time zones.

What is an ISO 8601 timestamp?

ISO 8601 is an international standard for expressing dates and times. Format: YYYY-MM-DDTHH:MM:SSZ. For example: 2026-05-15T14:30:00Z means May 15, 2026 at 2:30 PM UTC.

What is a Unix timestamp?

A Unix timestamp (or epoch timestamp) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. It is widely used in programming and APIs. Example: 1747318200 = May 15, 2026 at some point in UTC.

How do I convert a Unix timestamp to readable time?

Paste the 10-digit Unix timestamp (seconds) into the input above and click Convert. The tool shows the equivalent local time in six major time zones.

What does the Z at the end of a timestamp mean?

Z stands for Zulu time, which is another name for UTC. A timestamp ending in Z is unambiguously in UTC — no time zone conversion needed to determine the UTC value.
