Licenses that renew in October
DORA sets one expiry date per license type, so renewals arrive in waves. 91,502 active licenses expire in October, across 35 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 91,502 licenses share October.
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.
