About the Unix Timestamp Converter
A Unix timestamp counts seconds since 1 January 1970 UTC, the epoch, and it is how most systems store time. This converter turns a timestamp into every form you might need: the ISO 8601 string, the RFC 2822 string, the date in a chosen time zone, the day of week, day of year, ISO week, and a human relative form such as "3 hours ago". It also accepts a date in almost any format and shows its timestamp, so it works in both directions.
Both seconds and milliseconds are detected automatically, as are microsecond and nanosecond values, so a timestamp pasted from any source is understood. Paste several, one per line, to convert a column. The word "now" gives the current moment.
This is the tool for reading a timestamp from a log or database and for finding the timestamp of a given date. For arithmetic on dates, the Date Difference and Add or Subtract Time tools; for time-zone comparison, the Timezone Converter.
How to use
- Paste a timestamp or a date, or type "now".
- Choose a time zone if you need one other than local and UTC.
- Read every form on the right.
Common questions
- Does it detect seconds versus milliseconds?
- Yes, automatically, along with microseconds and nanoseconds, from the number of digits.
- Can I convert a date to a timestamp?
- Yes. Paste a date in almost any format and the timestamp is shown along with the other forms.
- What is the epoch?
- Midnight UTC on 1 January 1970, the point Unix time counts from.
- What does "relative" mean?
- A human phrase like "in 2 days" or "5 minutes ago", relative to now.
