Random number from 1 to 12

Twelve is everywhere in daily life: twelve months, twelve hours on a clock face, twelve signs of the zodiac, a dozen eggs. This page is ready with the range 1 to 12. Press Generate and each number has a chance of one in twelve, about 8.3%.

Ideas for a number from 1 to 12

  • A month. January is 1, December is 12. Pick a month for a trip, a birthday-month game or a themed party.
  • An hour. Choose a time on a clock face for a practice exercise in telling time, or for a reminder.
  • Times tables. Generate two numbers with No repeats off and multiply them. It is a quick drill, and every pair from 1 × 1 to 12 × 12 can come up.
  • A dozen of anything. Twelve questions, twelve cards, twelve songs on a list.

Months and shared birthdays

Here is a classroom surprise: in a group of only five people, the chance that at least two were born in the same month is about 62%. With four people it is about 43%. Most people guess much lower. Try it: generate 5 numbers with No repeats off and see how often one repeats. (Real birth months are not perfectly even, but the result stays close.)

Twelve also matches a d12, the twelve-sided die of role-playing games. If you want to see one tumble, open the d12 roller. And for a random day rather than a month, the 1 to 31 page picks a day of the month.

Picking several numbers from 1 to 12

How it works

  1. The range is set

    The lowest and highest numbers for this page are already in the sentence at the top, and both can come up. Nothing to type before your first pick.

  2. Pick your number

    Press Generate or the Space bar, or tap the number. The reel rolls like a slot machine and stops on the result.

  3. Change it if you need to

    Tap how many numbers you want in the sentence to get up to 20 at once; No repeats keeps them all different. Tap either end of the range to type a new one.
