Licences that renew in September
DORA sets one expiry date per licence type, so renewals arrive in waves. 119,568 active licences expire in September, across 8 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 119,568 licences 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.
