Most forms operate based on the defined state and federal holiday schedules. For federal holidays, you consult the National Office of Personnel Management, and for Oregon holidays, you consult ORS 187.010. ORS 187.010 is what establishes state holidays and gets updated periodically to add things [e.g. Juneteenth was added in 2021]. There can be disagreements between federal and state holidays, for instance, Columbus Day will be October 13, 2025, on the federal calendar and is a federal holiday, but it is not a recognized state holiday under ORS 187.010. There are other days that may not show on either federal or state holiday lists, such as the day after Thanksgiving.
There is constant confusion about state holidays because a simple internet search for “Oregon State Holidays” will bring up the “State Observed Holidays – Closures” list from the Public Utility Commission [PUC] as the first link available, stating what days they are not open. On that PUC list, the day after Thanksgiving is plainly and clearly listed as a holiday. That is the confusion – State HR Policy No. 60.010.01 establishes the day after Thanksgiving as a paid holiday but only for state employees. Agencies can choose their observances somewhat separately from the state law, so if the Water Resources Department wanted to give their employees the day on March 22 for World Water Day [true story, actual day] and publish that they were observing the day as a holiday, they can do that, but it doesn’t make March 22 a state holiday. Holidays would only be established by legislation or by executive order [governors can declare specific days as holidays, though Governor Kotek has not declared any state holidays under her ORS 187.020 authority to date].
Nonetheless, be aware that the PUC website only tells you when employees will be in the office at the PUC, it does not tell you what Oregon law has declared an official “holiday.” To that end, the day after Thanksgiving is not technically a holiday, though many organizations such as title companies may shut their doors on that day. Keep an open line of communication with your various settlement service offices when you get close to a holiday; plan your deadlines and closing dates around when the banks, title, and escrow offices are open.
