Thanksgiving to New Year’s Day: Hours for government offices, libraries and transit

• A county employee holiday list is about staff days off, not each window’s hours; when a county winter closure says “many county services” or “most county offices” are closed, that is not all of them.
• A library’s closure list says whether branches open; it does not say that online services stop.
• A standing holiday schedule does not by itself promise extra New Year’s Eve service or free rides (VTA’s standing note does add light rail on New Year’s Eve; see below); for service and fares on New Year’s Eve 2026, look for each agency’s notice for that night.

• California DMV (all offices): closed all day Nov 26, Nov 27, Dec 25 and Jan 1, 2027 [Dated list]. Dec 24 and Dec 31 are not on the DMV closure list [Not published]. The list covers offices only; for online services and kiosks, see the DMV site.
• Social Security (all offices): closed Nov 26 and Dec 25 [Dated list]. Closed Jan 1, 2027 [Standing rule: SSA says all offices close on federal holidays, and OPM’s 2027 federal holiday schedule lists January 1]. Nov 27, Dec 24 and Dec 31 are not federal holidays and are not on SSA’s holiday list [Not published]. Phone and online services are not part of this list.

These are the county social services departments that handle CalFresh, Medi-Cal, CalWORKs and other benefits. A county holiday is not always spelled out for each benefits window; each line says how far the notice goes.

• Alameda County Social Services Agency: county offices closed Nov 26, Nov 27 and Dec 25 [County notice]. Dec 24 and Dec 31 are not on the county’s closure list [Not published]; the county’s list runs only through 2026, so Jan 1, 2027 is [Not published].

• Marin County HHS: Nov 26, Nov 27 and Dec 25 are county holidays [County holiday list], with no separate notice for the benefits windows. Dec 24, Dec 31 and Jan 1, 2027 [Not published]: the county calendar we read runs only through 2026.

For December 26–31 the county says only that “many county services” close, so whether HHSA opens on Dec 31 is [Not published].
• San Francisco HSA: the 1460 Mission service center says it is open “excluding City holidays”, and the City’s 2026 holiday data lists Nov 26, Nov 27 and Dec 25, so that center is closed those three days [Standing rule]. Other service sites, Dec 24 and Dec 31 are [Not published]; the City holiday data runs only through 2026, so Jan 1, 2027 is also [Not published].
• San Mateo County HSA: the county’s employee resolution lists Thanksgiving, the day after, Christmas Day and New Year’s Day as county holidays, and HSA’s overpayment repayment window at 1 Davis Drive (Belmont) is open “excluding holidays”, so that window is closed Nov 26, Nov 27, Dec 25 and Jan 1, 2027 [County holiday list]; the regional benefits offices have no notice of their own. The county sets three winter recess days between Dec 26 and Dec 31, when departments may cut to minimum staffing or close; HSA’s plans for Dec 24 and Dec 31 are [Not published].
• Santa Clara County Social Services Agency: the benefits application page says “offices are closed for county holidays”, and the county holiday list includes Nov 26, Nov 27, Dec 25 and Jan 1, 2027, so the Senter Road, Mountain View and Gilroy application offices are closed those four days [Standing rule]. Dec 24 and Dec 31 are not county holidays [Not published].
• Solano County Employment & Eligibility: the county’s human resources page lists Nov 26, Nov 27, Dec 25 and Jan 1, 2027 as county holidays [County holiday list], with no separate notice for the benefits offices.
