Licences that renew in October
DORA sets one expiry date per licence type, so renewals arrive in waves. 90,352 active licences expire in October, across 35 types.
Why they all fall due together
Colorado does not renew licences on their anniversary. DORA sets a fixed expiry date per licence type — and often a parity, odd or even years — so every holder of that type renews on the same day. That is why 90,352 licences 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.
