Limits and safe use
Do not change a correct clock just because a reminder says to fall back.
This tool offers general information. It does not replace a doctor, lawyer, accountant, or emergency service.
Yes records your assertion, not independent verification. The checklist prioritizes missing evidence in the order shown; it does not calculate risk or certify an outcome. Nothing is submitted to any agency, provider, seller, or employer.
Source notes and currentness
NIST says radio-controlled clocks can receive DST information, while their zone and DST settings still matter.
- NIST — Daylight Saving Time Rules
In observing U.S. locations, DST ends November 1, 2026 at 2 a.m. local time, repeating the 1 a.m. hour. Many U.S. territories, Hawaii, and most of Arizona do not observe DST. Local time conversion depends on current time-zone rules.
Publication/effective date: 2026 DST dates. Checked 2026-11-01.
- Alameda County Registrar of Voters — Official Election Site
The official county calendar identifies November 3, 2026 as Election Day. Other calendar entries and local voting arrangements apply to Alameda County, not the entire United States.
