What is date sorting?

Date sorting is the process of arranging dates in chronological order, either from oldest to newest (ascending) or newest to oldest (descending). This is essential for organizing logs, events, schedules, and any time-based data. The challenge lies in the variety of date formats used worldwide—from ISO 8601 to regional formats like MM/DD/YYYY (US) or DD/MM/YYYY (European)—which can make sorting difficult without proper parsing.

Tool description

This tool sorts date strings in various formats chronologically. It can automatically detect date formats or allow you to manually specify the format (ISO 8601, US format, European format, Unix timestamps, and more). You can choose to sort dates in ascending order (oldest first) or descending order (newest first), and optionally skip invalid dates that cannot be parsed.

  • 15+ supported formats - Including ISO 8601, US (MM/DD/YYYY), European (DD/MM/YYYY), Unix timestamps, and formats with time
