Can the moon stay up all day in Phnom Penh? No. That needs a latitude past 61.4°, and Phnom Penh is 11.6°N — about 50° short — so the moon rises and sets on essentially every date. What does happen roughly once a month is a date with no moonrise, or no moonset: the moon comes up about 50 minutes later each day, and eventually one of the two slips past midnight.
All 13 of them, in Asia/Phnom_Penh local time. A full moon is one instant worldwide, so the clock time is Phnom Penh's own.

Reading the table. Moonrise and moonset are for the local date shown, which is what the calculator gives for that date. Rides highest is the altitude at the moon's culmination nearest the full-moon instant, and carries its own date: a full moon culminates within about half a day of the instant, so it lands on the day before roughly as often as the day after. "None" means that date genuinely has no moonrise (or no moonset), which happens about once a month everywhere.
2026's nearest full moon over Phnom Penh is Thursday, December 24 at 356,740 km, and the farthest is Sunday, May 31 at 406,135 km — a 14% difference in distance, and so about that much difference in apparent width. The nearer one is what gets called a supermoon.
Moon times for Phnom Penh are computed from the full Meeus lunar theory — the complete 47.A and 47.B periodic tables — at the city's latitude (11.5564°) and longitude (104.9282°), then converted to local time in the Asia/Phnom_Penh timezone. Rise and set are found by sampling the moon's altitude across the day and bisecting each horizon crossing, because the moon moves about 13° a day and no single position describes it. Against US Naval Observatory tables the result agrees to the displayed minute.
Why moonrise has no fixed time. The moon travels eastward against the stars as it orbits, so the Earth has to turn a little further each day to bring it back to the horizon — about 50 minutes further. That is why a page of moon times for Phnom Penh cannot be written down the way sunrise times can: the cycle is 29.5 days long and does not fit the calendar. Roughly once a month a date in Phnom Penh has no moonrise at all, or no moonset, simply because the event slid past midnight. The calculator says so in words rather than leaving a blank.
The 18.6-year cycle. Moonrise in Phnom Penh is not a fixed direction. Over the moon's 18.6-year cycle the rise point sweeps 59° of horizon, from 61° ENE at its northernmost to 119° ESE at its southernmost. That is 11° wider than the sun ever manages from Phnom Penh, whose rise point is confined to 48° between the solstices — the moon's orbit is tilted a further 5.1° to the ecliptic, so it overshoots the sun's limits in both directions.
The moon passes directly overhead in Phnom Penh: its latitude falls inside the band the moon's declination covers, so at some point in the cycle the moon stands at the zenith, while at the other end it climbs no higher than 50°. Everything the moon does over Phnom Penh happens between those two figures, and neither of them shifts — they follow from the city's latitude and the tilt of the moon's orbit, not from the calendar.
What time does the moon rise in Phnom Penh tonight?
Tonight's moonrise, moonset and highest point for Phnom Penh are at the top of this page, computed in your browser for Asia/Phnom_Penh. There is no single answer to keep on file: the moon rises roughly 50 minutes later each day, so tonight's time is about 50 minutes later than last night's and the whole cycle repeats only every 29.5 days — which is why this page's fixed reference is the geometry of Phnom Penh's horizon rather than a table of times.
When is the next full moon in Phnom Penh?
All 13 full moons of 2026 are listed above in Phnom Penh local time, from Saturday, January 3 to Thursday, December 24. The panel at the top of the page shows the next one counting from today. A full moon is a single instant worldwide — the moment the moon is opposite the sun — so it lands at a different clock time in every timezone, and occasionally on a different calendar date.
How high does the moon get in Phnom Penh?
Phnom Penh is close enough to the equator that the moon can pass directly overhead: at the top of its 18.6-year cycle it culminates at the zenith, 90° above the horizon. At the other extreme it culminates at about 50°. The moon is never confined to one part of the sky here — over a single month it climbs through most of that range.
Does the moon ever stay up all day in Phnom Penh?
No. That needs a latitude past 61.4°, and Phnom Penh is 11.6°N — about 50° short — so the moon rises and sets on essentially every date. What does happen roughly once a month is a date with no moonrise, or no moonset: the moon comes up about 50 minutes later each day, and eventually one of the two slips past midnight.
