What is a Timestamp Converter?
A Timestamp Converter transforms between Unix timestamps (the number of seconds since January 1, 1970, 00:00:00 UTC) and human-readable date/time formats. Unix timestamps are widely used in programming, databases, APIs, and logging systems.
Common Timestamp Formats
- Unix Seconds: e.g.,
1693891200- Standard 10-digit timestamp. - Unix Milliseconds: e.g.,
1693891200000- Used by JavaScript and many APIs. - ISO 8601: e.g.,
2023-09-05T12:00:00Z- Universal standard format. - RFC 2822: e.g.,
Tue, 05 Sep 2023 12:00:00 GMT- Email-friendly format.
How to Use This Tool
- Single Conversion: Enter a Unix timestamp or select a date to instantly see all formats.
- Batch Conversion: Paste multiple timestamps (one per line) to convert them all at once.
- Quick Buttons: Use preset buttons like "Now", "Start of Today", or "1 Week Ago" for common timestamps.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (the Unix epoch). It's a simple, timezone-independent way to represent points in time.
Why are some timestamps 10 digits and others 13?
10-digit timestamps are in seconds (Unix time), while 13-digit timestamps are in milliseconds (used by JavaScript's Date.now() and many APIs).
What is the maximum Unix timestamp?
The maximum 32-bit Unix timestamp is 2,147,483,647 (January 19, 2038). After this, systems using 32-bit integers will overflow. Modern systems use 64-bit integers, which won't overflow for billions of years.
