Federal hemp status ends for non-naturally-producible cannabinoid products
Regulatory deadlines
First of two federal hemp dates now fixed in statute. H.R. 6500 (the Continuing Appropriations and Extensions Act, 2027, signed September 2, 2026) delayed most of the November 2025 hemp redefinition to December 11, 2026 — but products containing cannabinoids "not capable of being naturally produced by a Cannabis sativa L. plant" lose federal hemp status on the original date, November 12, 2026. Cannabinoids the plant can produce but that are converted or synthesized outside it (much of the delta-8 market) stay covered until December 11. See the December 11 entry for the main effective date.

Cannabis retail sales holidays — the planning guide

How the calendar is kept

Sourced, not scraped

A date is confirmed only when it comes from the organizer, the regulator or an official government source. Anything from a third-party list is shown as est. until we’ve checked it, and every item shows the date it was last checked.

Reviewed monthly

Every item inside the next 120 days is re-checked against its source each month; recurring dates (sales holidays, tax deadlines) are rolled forward a year ahead. Legislation with a moving effective date is flagged date pending.

Free to be listed

Organizers get a free profile in the Register and can claim it to keep dates current. Placement is never sold; if that ever changes, it will be labelled.

Run an event, or spot a wrong date?

Send it in — a person reads every submission and checks it against the source before it goes on the calendar.
