## Licenses that renew in September

DORA sets one expiry date per license type, so renewals arrive in waves. 119,568 active licenses expire in September, across 8 types.

### Why they all fall due together

Colorado does not renew licenses on their anniversary. DORA sets a
**fixed expiry date per license type** — and often a parity, odd
or even years — so every holder of that type renews on the same day. That is
why 119,568 licenses share September.

It is in DORA's data, spread across a 344-row table of codes. Nobody
publishes it as a calendar, which is what this page is.
