Frequently asked questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (midnight UTC), not counting leap seconds. It's a standard way computers represent time, used across most programming languages and databases.
Why are there two different timestamp lengths?
Unix timestamps are typically in seconds (10 digits). JavaScript uses milliseconds (13 digits) for Date.getTime(). Our converter handles both — enter a seconds timestamp in the input and see the human date.
Does this handle time zones correctly?
Yes — the human date you enter is treated as local time. The converter shows both local and UTC representations. The Unix timestamp itself is always UTC-based, which is why it's a universal reference.
Convert Unix timestamps to human-readable dates and vice versa. Enter a numerical timestamp to see the corresponding date in local, UTC, and ISO 8601 formats — or pick a date to get its Unix timestamp.
Essential for developers working with APIs, databases, or log files that use epoch-based timestamps. All conversion happens client-side with no server requests.
