Good to know
When does the August 2026 partial lunar eclipse begin?
NASA lists the observable partial eclipse beginning at 02:34 UTC on August 28, 2026. Greatest eclipse follows at 04:13 UTC.
Why does this countdown use 02:34 UTC?
NASA lists penumbral contact at 01:24 UTC, but the observable partial eclipse begins when the Moon enters Earth’s umbra at 02:34 UTC. This page follows that partial-phase start because its countdown is specifically for the partial lunar eclipse beginning.
