When is the full moon?

The next full moon is on 26 October 2026 at 05:12 Poland time (CET). Find the live countdown and complete calendar on this page.

The current phase and disc illumination are shown live at the top and in ‘Today's moon phase’. Values update continuously using Polish local time.

New moon is when the disc is practically invisible (0% illumination), starting a new cycle. Find upcoming new moon and quarter dates under ‘Upcoming moon phases’.

Some studies suggest slightly later sleep onset and shorter sleep near full moon. Bedroom light and evening routine matter most, so focus on a dark, calm sleep environment.

It is the fraction of the visible disc lit by the Sun. 100% is full moon, 0% is new moon, and around 50% corresponds to first or last quarter.

These folk names derive mainly from North American traditions and were popularised by the Farmers’ Almanac. They describe seasons and natural events, not astronomical phenomena.

A full moon near perigee, the closest point to Earth in its orbit. The disc appears slightly larger and brighter than usual.

A common name for the second full moon in a calendar month, occurring roughly every 2–3 years. It does not refer to colour. Our calendar shows both dates for such months.

A complete cycle from new moon through first quarter, full moon and last quarter back to new moon averages about 29.5 days (a synodic month).

A quarter moon occurs when exactly half the disc is illuminated (50%). The first quarter falls between new and full moon and is visible in the evening; the last quarter falls between full and new moon and is visible towards morning.

They describe the disc's appearance. Nów comes from the Polish word for ‘new’. Pełnia describes a ‘full’, entirely lit disc. Kwadra comes from Latin quadra/quadrans (‘quarter’), reflecting positions in the cycle.

Low in the sky, moonlight travels through more atmosphere, which scatters blue light while allowing red and orange through. The rising Moon may therefore look warmer, becoming silvery higher in the sky.

The Moon is tidally locked to Earth: one rotation takes as long as one orbit. The same hemisphere faces us; only the lit fraction changes.

Strong evidence is limited. A small sleep effect around full moon is better documented. If your energy drops, first focus on a dark bedroom and regular sleep times.

Dim bright lights an hour before bed, lower screen brightness or use a warm setting, and cover windows to block outside light. Blue-light-blocking glasses and an eye mask may also help.

Treat the calendar as a gentle prompt, not a rigid plan. If you sleep worse around full moon, plan a calmer routine and better darkness. Regular sleep times and evening light matter most.
