How it works

  • Range draws use rejection sampling and a partial shuffle of eligible positions. Selected positions are unique within each draw; optional exclusion removes them from later draws. Calendar days are evaluated in UTC, with both endpoints included before weekday filtering.
  • Choices and results are processed in this tab and are not automatically saved or uploaded. This is a casual selection tool, not a certified lottery or a prediction of real outcomes.

Assumptions and limitations

The range includes both endpoints and uses Gregorian calendar days, not elapsed hours. Weekday filters do not exclude public holidays or check anyone’s availability. An empty filtered range must be widened or changed before drawing.

How to use this tool

Set the range and how many values to draw. Date filters use calendar weekdays. Each draw has distinct values. Keep permits repeats in a later draw; Remove excludes winners until reset or a pool change. Copy exports the displayed result.

When to use it

Choose a date for a creative challenge, a historical research prompt or a sample record. Set a start and end date, then decide whether every calendar day or only particular weekdays should enter the draw.

Worked examples

  • Draw a weekday within one week

    From March 1 to March 7, 2027, the Monday–Friday filter leaves five dates. Each has a 1-in-5 chance in a single-date draw. Selecting weekends instead leaves March 6 and March 7 as the two candidates.
