Moon Calendar

How to read the moon calendar day by day

Each cell is calculated for midday of that date. The small moon drawing shows the phase, the number next to it is the lunar day, and the short line underneath is the traditional hint for that day — haircut, rest, a clear-out, a quiet evening.

The lunar day is counted from the Moon’s age: the time passed since the last New Moon. The first day after the New Moon is lunar day 1, the next is day 2, and so on up to 30. Because a lunar month lasts about 29.5 days, not every cycle reaches day 30, and because the count is taken at noon, a date near midnight or in another time zone can shift by one lunar day. If an exact moment matters to you, use the phase calculator below the calendar rather than the grid.

A quick way to orient yourself:

• Lunar days 1–14: the waxing half. The tradition links it with starting, adding and growing.
• Around days 15–16: the Full Moon, the peak of the cycle.
• Days 16–30: the waning half, linked with finishing, trimming and clearing.

Which moon tool do I need?

The shelf has grown, so here is a short map by question:

• “What is the Moon doing this month?” — the live calendar on this page.
• “What was the phase on a specific date and time?” — the moon phase calculator: angle, illumination, age and sign.
• “What Moon was I born under?” — the lunar birthday page, with your lunar day and its reading.
• “What does lunar day 12 mean?” — the full guide to lunar days 1–30.
• “When exactly is the next Full Moon?” — the yearly phase calendars, with every principal phase to the minute.
• “Can I actually see it tonight?” — moonrise and moonset for your coordinates.

A simple monthly routine with the Moon

If you would like the Moon as a rhythm rather than a rulebook, try three touchpoints a month:

1. New Moon: write one intention for the month — small enough to check off.
2. Full Moon: look at what has piled up, physically or emotionally, and choose one thing to let go of.
3. Last quarter: a practical tidy — drawers, inbox, fridge.

That is enough to feel the month has a shape. Keep notes on energy and sleep for a few cycles; you may find a pattern, or discover you have none, and both answers are honest ones.

What the calendar can and cannot tell you

Phases and lunar days are astronomy, computed for real. The hints about haircuts, cleaning or starting projects are folk tradition — a charming way to plan, not a law of nature. Nothing bad happens if you cut your hair on the “wrong” day, and no Moon phase replaces medical advice, a good night’s sleep or common sense.
