Random Date Generator: Pick Dates Across Custom Eras, Years & Formats

Whether you are generating realistic mock database records for software QA testing, picking random historical events for history trivia, finding a birthday for roleplaying characters, or scheduling a surprise anniversary outing, our Random Date Generator makes temporal randomization effortless.

Filter by past, present, or future date boundaries, include or exclude specific days of the week (like weekends or business weekdays), generate accompanying random timestamps, and export results in international ISO 8601 (YYYY-MM-DD), US (MM/DD/YYYY), European (DD/MM/YYYY), or Unix epoch formats. Hit Spacebar for instantaneous rolls.

Frequently Asked Questions

Does this random date generator correctly handle leap years?

Yes. The generator adheres strictly to the Gregorian calendar rules, accurately factoring in leap years (such as February 29th on years divisible by 4, except century years not divisible by 400) and varying month lengths (28, 30, and 31 days).

Can I generate random birthdays for test profiles?

Yes! Simply set the start year (e.g. 1960) and end year (e.g. 2005) to generate realistic birthdates for mock user profiles, demographic studies, or fiction writing.

How can I generate random timestamps with hours and minutes?

Toggle the "Include Random Time" switch to append randomized 24-hour time values (HH:MM:SS) to each date, perfect for testing database timestamp sorting and API payload serialization.

Can I generate dates in chronological order?

Yes. When generating multiple dates, you can choose to sort them in Ascending (oldest first), Descending (newest first), or Raw Random order with a single click before exporting.

Is there any limit to how many dates I can generate?

You can generate batches of up to 500 dates per click for free. Since processing occurs instantly on your device, there are no API rate limits or wait times.

Can I export generated dates to CSV or JSON?

Yes. Click "Copy All" to grab newline-separated values for spreadsheets, or select "Export JSON" to paste structured date arrays directly into your mock APIs and frontend test fixtures.
