Random Date Generator

A random date generator creates one or more dates chosen uniformly at random within a user-defined range. Each date is produced using the Web Crypto API (crypto.getRandomValues), which provides cryptographically strong random numbers — far more statistically sound than Math.random() for applications that require unbiased sampling.

Random dates are useful whenever you need test data, random scheduling, statistical sampling, or game mechanics. You can generate up to 100 dates at a time, optionally including a random time component down to the second, and copy all results to your clipboard in one click.

How it works

A random timestamp is picked with: t = startMs + floor(random() × (endMs − startMs)), where random() uses crypto.getRandomValues for uniform distribution. The timestamp is then converted to a YYYY-MM-DD (or YYYY-MM-DD HH:MM:SS) string.

Use cases

  • Generating realistic mock data for databases and APIs
  • Randomly scheduling events or appointments in testing environments
  • Sampling random dates for statistical or research purposes
  • Creating random birthdays or event dates for demo applications
  • Picking random dates for games, raffles, or creative projects
