Usage notes
- Unix epoch: January 1, 1970 00:00:00 UTC.
- Most APIs use seconds. JavaScript uses milliseconds.
- The current timestamp updates live every second.

Frequently Asked Questions
- What is a Unix timestamp?
- A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It's used universally in programming for storing and transmitting dates.
- Seconds vs milliseconds?
- Most backend systems and APIs use seconds (10 digits, e.g., 1700000000). JavaScript's Date.now() returns milliseconds (13 digits, e.g., 1700000000000). Our tool supports both.
- What happens in 2038?
- 32-bit systems storing timestamps as signed integers will overflow on January 19, 2038 (the 'Year 2038 problem'). 64-bit systems and JavaScript handle dates far beyond this.
- What date formats can I enter?
- Any format JavaScript's Date constructor accepts: ISO 8601 (2024-01-15T10:30:00Z), RFC 2822, or informal formats like 'January 15, 2024 10:30 AM'.
