Random Date Picker

Each draw is a uniform pick from Math.random(), with Fisher-Yates shuffling for unique mode. For audit-grade randomness with proofs, you'd want a verifiable source like drand or a hashed block — this tool is the every-day kind of random.

With Unique on, no — you'll get a "not enough days" message. With Unique off, repeats are allowed and you can draw any count.

Dates only, not timestamps. If you need a random instant within a day too, draw a random integer 0–86399 separately and add it as seconds.

Not from the result alone — a date on a screen carries no evidence of how it was produced. If a draw has to be defensible, publish the rule and the inputs before drawing (the range, the count, the exclusions), and have someone outside the process witness or reproduce it. Randomness makes a draw unbiased; only a published procedure makes it verifiable.

It changes which days can be drawn, not the fairness among the days that remain: each eligible weekday is still equally likely. What it does change is the shape of any pattern you read into the result — a month with a holiday you did not exclude still has its holidays in the pool, and a range that starts mid-week has slightly different counts per weekday, which is worth checking when the number of draws is small.
