On 26 October 2026, the Moon reaches its full phase at 04:12 UTC. In Los Angeles it is 21:12 on 25 October. In London it is 04:12 on 26 October. Both calendar dates are correct for their locations.
Follow the instant, not just the day.
Phase tables record a moment in a common time standard. This one is 04:12 UTC. Los Angeles is seven hours behind UTC on that date, so the local clock reads 21:12 on the previous evening. London has returned to GMT by then, so its clock reads 04:12 on the 26th. India is five hours and thirty minutes ahead of UTC, making the time 09:42 on the 26th.
If a headline gives only “25 October” or “26 October,” look for its time zone. Without a location or UTC time, the date is incomplete. The same rule applies to a planetary station or any other event defined at a global instant.
The phase instant is global. A moonrise, visible crescent, or local observance depends on location and may need a different calculation. Do not transfer the phase timestamp to those questions.
Where astrology enters
Astrologers may discuss a full moon within a particular zodiac and interpretive tradition. That reading is separate from the clock conversion above. A personal claim needs the person's chart details and stated calculation rules; a city date alone does not supply either.
If you are comparing two astrology posts, first ask whether they refer to the same UTC instant. Then check their time zones. If those match and the posts still differ, the next questions are their calculation settings and sources.
