How it works
- The browser chooses an entry using cryptographic randomness with rejection sampling. Every remaining line has one chance; repeating a line gives that choice additional chances. The wheel animation presents the result already chosen.
- 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
This selects a month name, not a particular day or a real appointment. Month length is not used as a weight. For an actual date range, use the date picker and review holidays or scheduling constraints separately.
How to use this tool
Review the choices, select a choice set when offered, and spin. The result card lets you spin again, remove that occurrence or close. Editing the list changes the candidate pool; a new choice set restores its reviewed defaults. Sound, confetti and animation have separate switches.
When to use it
Assign a month to a photo challenge, a seasonal writing task or a sample birthday record. Selecting months directly makes each month equally likely, regardless of whether it contains 28, 29, 30 or 31 days.
