Common Date Format Reference
- ISO 8601:
2026-03-17— international standard, unambiguous, sorts correctly as a string - US:
03/17/2026— common in American applications - European:
17/03/2026— common in European applications - Unix timestamp:
1773878400— timezone-independent, easy to compare and sort - RFC 2822:
Tue, 17 Mar 2026 00:00:00 +0000— used in email headers
Use the Date Formatter at techconverter.me to convert any date between any format, with timezone support, locale-specific output, and batch conversion for multiple dates at once.
Examples
Example 1: Common Format Conversions
/* Input: ISO 8601 */
2026-03-17T14:30:00Z
/* Output in various formats */
US format: 03/17/2026
European format: 17/03/2026
Long format: March 17, 2026
Short format: Mar 17, 2026
Unix timestamp: 1773880200 (seconds)
Unix ms: 1773880200000 (milliseconds)
RFC 2822: Tue, 17 Mar 2026 14:30:00 +0000
RFC 3339: 2026-03-17T14:30:00+00:00
Example 2: Unix Timestamp to Human-Readable Date
/* Input: Unix timestamp */
1773880200
/* Output */
UTC: 2026-03-17 14:30:00 UTC
ISO 8601: 2026-03-17T14:30:00Z
US format: 03/17/2026 2:30 PM
Long format: Tuesday, March 17, 2026 at 2:30 PM UTC
/* Millisecond timestamp */
1773880200000 → same result (auto-detected as ms)
/* Common mistake: ms timestamp treated as seconds */
1773880200000 seconds → year 58,148 (clearly wrong)
/* The formatter detects this and warns you */
