Random Number 1–12 Generator
Generated using the Web Crypto API for cryptographically secure randomness.
Pick a number between 1 and 12
This tool picks a whole number from 1 to 12, each with an equal 8.33% chance. Twelve is one of the most useful everyday ranges: months of the year, hours on a clock face, and the d12 die from tabletop games all map straight onto it.
Every draw uses the Web Crypto API rather than Math.random(), so the result is cryptographically secure, uniform, and unpredictable.
Use cases
- Pick a random month for a draw, rotation, or planning exercise
- Choose a random hour on a 12-hour clock face
- Roll a d12 for tabletop games without the physical die
- Assign one of twelve players, zones, or zodiac signs
- Select a random jury member or panel seat from twelve
Frequently asked questions
Is every number equally likely?
Yes. Each number from 1 to 12 has an equal 8.33% chance on every generation, mapped with rejection sampling so no value is favored.
Is this the same as rolling a d12?
Mathematically, yes — both pick a uniform integer from 1 to 12. For the dice look and feel, use the dedicated d12 roller; this page serves the plain “random number 1–12” intent.
