According to the US Naval Observatory's 2026 seasons table in UTC, did the September equinox occur during 22 September 2026 UTC?

Answer

false
source_1
US Naval Observatory 2026 seasons API, UTC: https://aa.usno.navy.mil/api/seasons?year=2026
true_rule
Return true if that September equinox timestamp is at or after 2026-09-22T00:00:00Z and strictly before 2026-09-23T00:00:00Z.
exclusions
Exclude meteorological autumn, the March equinox, the date in a US timezone and claims that day and night must each last exactly 12 hours.
false_rule
Return false if the table provides the September equinox timestamp and it falls outside that interval. Exactly midnight at the ending boundary is outside.
measurement
Select the Equinox entry with month=9 and year=2026 from the US Naval Observatory seasons API, with tz=0 and dst=false. Interpret its date and minute as UTC. This named table is authoritative if other almanacs differ slightly.
chain_window_role
The block window is a request anchor only. This is off-chain panel evidence. Resolve the event or measurement using the exact observation interval and rules above, not blockchain time or a rolling period.
