        How it works

        Twelve months, twelve equal segments: this wheel of months gives January to December the same chance on every spin. Choose a season, such as Jun to Aug, or 31 days or 30 days to narrow it. Each result shows the month's number, its days, its season north and south of the tropics, and which months start on the same weekday.

        A hosting rota in twelve spins

        A wheel does one thing a calendar cannot: it hands out months without anyone choosing. For a hosting rota, switch to Elimination and let each member take a turn. The month that comes up is theirs, and it leaves the wheel, so each time you spin the wheel, months already taken cannot come up again. If the group skips part of the year, open My list and press the cross beside those months.

        Why a fair wheel is not a fair birthday

        Each month gets one twelfth of this wheel, but months are not one twelfth of a year. Seven have 31 days, four have 30, and February has 28, or 29 in a leap year. By days alone, a random birthday is a little more likely to fall in a 31-day month than in February. For a day as well as a month, spin the birthday wheel.

        • Stuck on a holiday month? Spin the wheel with one season chosen, and the choice is down to three.
        • For a calendar quiz, spin and ask which other month starts on the same weekday. May and June are trick questions: nothing matches them.
        • In the lines under the results, a common year means one with no 29 February.

        Questions and answers

        Which seasons do the filters use?

        Meteorological seasons, which are blocks of three whole months. North of the tropics December to February is winter and June to August is summer, and south of them the two swap. Near the equator the year divides into wet and dry seasons instead, and these labels do not apply.

        Why do some months always start on the same weekday?

        A 31-day month is four weeks and three days, so the next month starts three weekdays later, and a 30-day month pushes it on by two. From 1 April to 1 July is 91 days, exactly 13 weeks, so those two always match. A leap day moves every later month on by one, which changes January's partners.

        Can I spin months only, with no season showing?

        Yes. Open My list, type the twelve months, press Spin only mine and spin. Your own months show alone, with no line underneath. The same list cuts the wheel to a school year, September to June, or takes a month twice for a double chance.

        How this list was compiled: The twelve months of the Gregorian calendar with their lengths and the leap year rule, checked against https://en.wikipedia.org/wiki/Gregorian_calendar (checked 2026-09-18). Seasons use the meteorological reckoning, in which each season is three whole calendar months and the two hemispheres are opposite, from https://en.wikipedia.org/wiki/Season (checked 2026-09-18). That page limits the four seasons to the temperate and polar regions: many tropical regions have a wet and a dry season instead, which is why each line says north or south of the tropics and not north or south of the equator. Astronomical seasons, which start at the equinoxes and solstices around the 20th to 23rd of March, June, September and December, are not used here. The last sentence of each line, on which months start on the same day of the week, is our own arithmetic from the month lengths, checked by computing every year from 1900 to 2100. Licence: own work
