Good to know
Colorado's biweekly 'State Frequent' filing calendar — the same 12 dates apply to gubernatorial and General Assembly candidate committees alike (county/local candidates use separate calendars). The first report's coverage begins the day after the prior period (2025-12-05 for continuing committees) or at formation. Weekend/holiday shifts are already reflected in the dates. Event-driven 24-hour major-contributor (≥$1,000) and 48-hour independent-expenditure reports are not listed here.
Electbase compiles these dates from official state sources as a workflow aid. It is not legal advice. Confirm every deadline with your filing authority before you rely on it.
