Timestamp/Epoch Converter - Unix Timestamp to Date | ZweiDeveloper Tools
Convert Unix timestamps to human-readable dates and vice versa. Supports auto-detection of seconds vs milliseconds, multiple output formats, and custom date patterns.
How It Works
Unix timestamps represent time as the number of seconds since January 1, 1970 (the Unix Epoch). This tool converts between Unix timestamps and human-readable dates. It auto-detects whether your input is in seconds or milliseconds (13+ digits). You can also enter a date string in common formats and get the corresponding Unix timestamp.
Practical Usage
Developers use timestamp conversion daily when debugging API responses, analyzing logs, working with databases, or configuring scheduled tasks. Common formats include ISO 8601 (2023-11-14T22:13:20Z), European (14/11/2023), and US (11/14/2023) date formats.

Key Facts
- Unix timestamps count seconds since the Epoch (1970-01-01T00:00:00Z)
- 13-digit timestamps are interpreted as milliseconds, not seconds
- ISO 8601 is the standard format for datetime interchange (YYYY-MM-DDTHH:mm:ssZ)
- The maximum practical timestamp is year 2100 (32503680000 seconds)
