Understanding Date Formats

ISO 8601 (YYYY-MM-DD): The international standard for date representation. Unambiguous and sortable. Recommended for databases and international applications.
US Format (MM/DD/YYYY): Common in the United States. Month comes first, which can be confusing for international users.
EU Format (DD/MM/YYYY): Used in most of Europe and many other countries. Day comes first, followed by month.
Unix Timestamp: Number of milliseconds since January 1, 1970 (Unix epoch). Used in programming and APIs for precise time representation.

Tips for Best Results

  • Use ISO format for database storage and international applications
  • Choose appropriate date range for realistic test data
  • Use timestamps for precise time calculations in programming
  • Consider timezone implications when using timestamps
  • Sort generated dates chronologically for better organization
  • Use quick range presets for common testing scenarios

Calendar Facts

  • The Gregorian calendar has 365 days (366 in leap years)
  • Leap years occur every 4 years, except century years not divisible by 400
  • The Unix epoch (timestamp 0) is January 1, 1970, 00:00:00 UTC
  • ISO 8601 is the international standard for date and time representation
  • Different cultures use different date formats, leading to potential confusion
  • The year 2038 problem affects 32-bit Unix timestamps (Y2K38)

Leap Year Rules

A year is a leap year if:

  • It is divisible by 4 AND
  • It is NOT divisible by 100 OR it IS divisible by 400

Examples: 2020 (leap), 2021 (not leap), 2000 (leap), 1900 (not leap)

Important Notes

  • Generated dates are sorted chronologically for easy viewing
  • All dates are valid within the Gregorian calendar system
  • Timestamps are in milliseconds (JavaScript standard)
  • Date ranges are inclusive of both start and end dates
  • Use appropriate format based on your target audience and application
