How it works
This random day of the week generator is a wheel of the seven days, each with a 1 in 7 chance. Each winner comes with the god or planet behind its name. Take winners off and no day comes up twice, which makes a rota.

Draw days for a rota with no repeats
To pick a random day of the week for each person, tap Take winners off (Elimination), so each winner leaves the wheel, then press Spin the wheel once per person. For office days, tap Monday to Friday first and spin three times: you get one of the 10 possible sets of three. Put them back refills the wheel.
Put names on the wheel, or only some days
Tap My list, type one name per line and press Spin only mine. With winners taken off, the first name out takes Monday, the second Tuesday and so on. In My list the cross beside a day takes it off the wheel: leave Tuesday, Thursday and Saturday for a training plan and each has a 1 in 3 chance.
- Spin seven times with winners taken off and the whole week comes back shuffled, one of 5,040 possible orders.
- Language drill: say the winner in French (from Monday: lundi, mardi, mercredi, jeudi, vendredi, samedi, dimanche) or Spanish (lunes, martes, miércoles, jueves, viernes, sábado, domingo).
- Israel and Saudi Arabia work Sunday to Thursday, Nepal Sunday to Friday. Open My list and press the cross beside each day off.
Questions and answers
Why do the days of the week come in this order?
Ancient astrologers ranked the planets slowest to fastest: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon. Each hour belonged to the next planet, and each day was named for its first hour. Twenty-four hours is three rounds plus 3, so each day lands three places along.
Which day is the first day of the week?
It depends on the calendar. ISO 8601, the international date standard, starts the week on Monday, and the wheel is laid out in that order. Many countries print Sunday first. On the wheel it changes nothing: all seven slices are the same size.
Does every day have the same chance?
Yes. Seven equal slices give each day 1 chance in 7. A random calendar date is less even: 2027 has 53 Fridays and 52 of every other day. Tap Count wins (Tally) and spin 70 times: the counts almost never all come out at 10.
