0 seconds agoWhat is a Unix Timestamp?
A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. This reference point is called the "Unix Epoch." It's a universal way to represent time that avoids timezone complications.
Seconds vs. Milliseconds
- •Unix (seconds): Traditional format, 10 digits (e.g., 1704067200)
- •Unix (milliseconds): JavaScript's Date.now() format, 13 digits (e.g., 1704067200000)
Common Date Formats
- •ISO 8601: International standard (2024-01-01T00:00:00.000Z)
- •UTC String: Human-readable UTC time
- •Local Time: Converted to your selected timezone
- •YYYY-MM-DD: Simple date format for databases
Why Use Timestamps?
- •Timezone Independence: Same value worldwide
- •Easy Calculation: Simple arithmetic for time differences
- •Compact Storage: Single integer vs. complex date strings
- •Sorting: Natural chronological ordering as numbers
- •APIs: Common format for data exchange
Quick Reference
- •1 minute = 60 seconds
- •1 hour = 3,600 seconds
- •1 day = 86,400 seconds
- •1 week = 604,800 seconds
- •1 year (approx) = 31,536,000 seconds
