Uses for Random Date Generation
Random date generators are used in many contexts: history teachers generate random historical dates for "what happened on this day" exercises; developers need random test data with valid dates; game masters generate random in-world dates; and scheduling tools use random dates for placeholder entries.

Frequently Asked Questions
How are random dates generated?+
The generator converts both dates to their Unix timestamp (milliseconds since 1 Jan 1970), picks a random value in between, then converts back to a date. This ensures perfectly uniform distribution across the range.
Can I generate dates in a specific decade?+
Yes. Set Start Date to 1 Jan of the first year and End Date to 31 Dec of the last year. For the 1990s: 01/01/1990 to 12/31/1999.
What is the oldest date I can generate?+
The HTML date input supports dates from the year 0001. For historical research, set the start date accordingly. The generator handles dates before 1970 (Unix epoch) correctly.
Can I generate only business days?+
Yes. Use the "Weekdays only (Mon-Fri)" filter. Note that public holidays are not excluded as they vary by country.
Can I generate multiple non-repeating dates?+
The current version allows repeats. For unique dates, generate more than needed and remove duplicates manually, or run multiple single-date generations.
What format should I use for international dates?+
ISO 8601 (YYYY-MM-DD) is the international standard and is unambiguous. US format (MM/DD/YYYY) and EU format (DD/MM/YYYY) can be confused with each other.
Can I pick a random birthday?+
Yes. Use 1 Jan of the birth year as start and today as end. The result is a random date within a person's possible lifespan.
What is the day of year?+
The ordinal day of the year: January 1 = Day 1, December 31 = Day 365 (or 366 in a leap year). Useful in astronomy, agriculture, and some business scheduling systems.
What are random dates used for in software testing?+
Test data generation needs realistic dates. Random dates help test edge cases: leap years, month boundaries, year boundaries, past and future dates. They also populate database fixtures and UI mockups.
Can this generate a random future date for a deadline?+
Yes. Set Start Date to tomorrow and End Date to your target window end. Use weekdays-only if you need business day deadlines.
