Months of the Year Wheel

Spin to select one of the 12 months of the year, each with equal odds. Useful for planning, writing prompts, and playful calendar picks.

Fair by design: each spin draws from your browser’s cryptographic random number generator, giving every entry an equal 1-in-12 chance. No server is involved.

One entry per line. 12 entries on the wheel.

About the Months of the Year Wheel

This wheel comes pre filled and ready to spin. Give it a whirl as is, or edit the entries in the box to make it your own. Every slice has equal odds, so the result is fair each and every time. When the wheel stops, the pointer at the top marks the winning slice.

Nothing you spin is uploaded anywhere. The Months of the Year Wheel runs entirely in your browser, and you can save your edits to your own device. When you want your visitors to spin the same wheel, copy the embed code under the wheel and drop it onto your page.

A random month is a handy little generator for planners and players alike. Writers spin it to set the season of a scene or to get a prompt like describe a memory from the month it lands on. Teachers use it to pick which month's birthdays get celebrated first or to quiz students on holidays and seasons. Families spin it to schedule who hosts the big dinner, and trivia hosts use it for month themed rounds. It even settles playful arguments about when to take a trip, since twelve equal slices mean no month gets favored, not even summer. The wheel shows the winning month clearly after each spin, so it reads well on a classroom projector. Narrow the list to a school term or a wedding window by editing the entries, and the odds rebalance to the months you keep.

The odds on this wheel

There are 12 slices, all the same size, so a given slice wins one spin with probability 1 ÷ 12 = 8.3%. Every spin is independent of the one before it, which means no result is ever due: after ten spins without a particular slice, the chance on the eleventh is still 8.3%.

Across several spins the maths follows the complement rule. The chance of a given slice coming up at least oncein ten spins is 1 − (1 − 1/12)10 = 58.1%. Edit the entry list and every figure here recomputes, because they are derived from the wheel rather than written down beside it.
