Unix Timestamp Converter
Convert between Unix timestamps (epoch time) and human-readable dates. Unix time counts seconds since January 1, 1970 at 00:00:00 UTC and is widely used in programming, databases, and APIs.
A Unix timestamp represents a point in time as the number of seconds elapsed since the Unix epoch: January 1, 1970, 00:00:00 UTC. This converter works in both directions. Enter a timestamp to see the date, or enter a date to get the timestamp.
Key formulas:
- Date to Timestamp: Calculate total seconds from epoch to the given date
- Timestamp to Date: Convert seconds back to year, month, day, hour, minute, second
- All calculations use UTC to avoid timezone ambiguity
Notable Unix Timestamps:
| Timestamp | Date (UTC) | Event |
|---|---|---|
| 0 | Jan 1, 1970 00:00:00 | Unix Epoch |
| 946684800 | Jan 1, 2000 00:00:00 | Y2K |
| 1000000000 | Sep 9, 2001 01:46:40 | Billennium |
| 1700000000 | Nov 14, 2023 22:13:20 | 1.7 Billion |
| 2000000000 | May 18, 2033 03:33:20 | 2 Billion |
| 2147483647 | Jan 19, 2038 03:14:07 | Y2K38 Problem |
The Y2K38 problem occurs because 32-bit systems store timestamps as signed 32-bit integers, which overflow on January 19, 2038. Most modern systems use 64-bit timestamps to avoid this limitation.
