Twelve Months, Equal Odds
Click Randomise and get one month back — January through December, each with exactly the same 1-in-12 chance of coming up. Useful for scheduling tasks with no fixed deadline, assigning monthly rotations without playing favorites, or any decision where "some month, it doesn't matter which" is genuinely the goal.
A new month is picked as soon as the page loads. Click the refresh icon for another one, or copy the result with one click.
How is the month picked?
The tool uses the browser's Math.random() to pick an index into the twelve
months, so every month has the same 1-in-12 probability regardless of how many days it
has or where it falls in the calendar. There's no weighting toward any particular month
and no memory of what was picked last time.
When would I need a randomly picked month?
- Team rotations — assign on-call months, presentation schedules, or recurring responsibilities without anyone picking favorites.
- Educational exercises — history projects ("research an event from this month"), seasonal writing prompts, or calendar-math practice.
- Goal setting — pick a random month to revisit and check in on a goal, adding a bit of built-in accountability. Combine it with the random date generator to land on a specific day within that month.
- Creative constraints — writers and artists can use a random month as a thematic prompt or content-calendar seed.
Is this the same as picking a random date?
No — this tool only returns a month name, not a specific day or year. If you need an actual date (for test data, a specific deadline, or anything that needs a full calendar date), use the random date generator instead, which lets you set a start and end date and returns a full date somewhere in between.
