Random Date Generator

Random Date Generator produces random calendar dates that fall within a range you choose, which is useful any time you need realistic but arbitrary dates rather than handpicking them.

Set a start date and an end date, decide how many dates you want, and the tool returns that many random dates spread across the interval, each formatted as a clean ISO string (YYYY-MM-DD) that sorts and parses predictably.

Developers reach for this when seeding databases, building test fixtures, fuzzing date-handling code or populating mock records with believable timestamps.

It is equally handy for spreadsheets and sampling tasks — for example picking random review dates, drawing a random day for a giveaway, or generating example birthdays for a demo.

The range is inclusive on both ends, so the start and end dates themselves can appear, and a single-day range simply repeats that day.

All generation happens locally in your browser using the built-in random number generator, so no data is sent anywhere and the tool works offline.

You can ask for anything from one date up to a thousand at a time, then copy the whole list to paste into your code, your spreadsheet or your test data with a single click.
