Pick a random calendar date between two boundaries, inspect the timestamp, and use secure browser randomness when it is available.
Date selected with secure browser randomness.
The tool parses the start and end dates, measures the number of whole days in the range, and then selects one day offset at random.
Dates are validated as real calendar days and sampled in UTC, which avoids local daylight-saving and timezone drift when stepping through the range.
Yes. The generator treats both the start and end dates as inclusive boundaries.
This keeps the output aligned to whole calendar dates rather than selecting arbitrary hours and minutes.
Yes. Any valid range works as long as the start date is on or before the end date.
It is the JavaScript millisecond timestamp for the selected date at 00:00:00 UTC.
Inclusive date ranges make it easier to reason about the earliest and latest possible outcomes.
Shorter ranges reduce the number of possible dates, while longer ranges create much wider variety.
Invalid calendar dates such as 2026-02-30 are rejected instead of being normalized automatically.
Random dates are helpful for test fixtures, seeded examples, and mock timelines.
