How it works

Draws the Moon of every day of a month or year for your place, with the illuminated fraction, moonrise and moonset in local time, the four principal phases, perigee and apogee with distances and the supermoons, as a print-ready PDF, SVG and PNG in 17 languages.

  • Phase and illuminated fraction at local noon of each day from the Skyfold ephemeris (truncated ELP-2000/82 Moon, VSOP87 Sun); principal phases where the Moon–Sun elongation is 0°, 90°, 180° and 270°.
  • Moonrise and moonset: upper limb on an ideal horizon with 34′ of refraction, topocentric (U.S. Naval Observatory convention).
  • Perigee and apogee: extrema of the geocentric centre distance; 2026 values agree with published tables within 3 minutes and 15 km. Supermoon after R. Nolle: a full or new Moon within 10 % of the perigee end of that orbit’s distance range.
  • Layout, fonts and the PDF/SVG/PNG writers are Printshop’s (Noto fonts, Intl month and weekday names, right-to-left order for Arabic).

Moonrise and moonset assume a flat horizon at sea level; hills and buildings delay rising and advance setting. The phase drawing shows the Moon as seen from the northern hemisphere, mirrored for southern places.

How to use the Skyfold Printable Moon Calendar

Print a Moon calendar for any month or year with phases, moonrise and moonset, perigee, apogee and supermoons for your place, in 17 languages.

What it is for

A Moon calendar on the wall answers everyday questions at a glance: when is the next full Moon, will there be moonlight for the evening walk, which nights are dark enough for stargazing, when is the Moon closest to the Earth. Generic calendars show phases only and use one time zone for everybody.

This tool draws the Moon of every day for your place: the illuminated fraction, moonrise and moonset in your local time, the four main phases with exact times, perigee and apogee with distances, and the supermoons. You get a print-ready PDF (one month per page or the whole year on one page), plus an SVG and a PNG of the first page. Month and weekday names come in all 17 site languages, and Arabic is laid out from right to left.

Worked example

Berlin (52.52, 13.405, Europe/Berlin), January 2027, one month per page, language Deutsch, A4 portrait, place line "Berlin".

The summary says the month has 1 full Moon and 1 supermoon and the calendar has 1 page. The page title reads "Januar 2027" and the week starts on Monday, as usual in German.

The Principal phases table lists the New Moon on 7 January at 21:24, the First Quarter on 15 January at 21:35, the Full Moon on 22 January at 13:17 and the Last Quarter on 29 January at 11:55.

Perigee and apogee shows the apogee on 7 January at 09:08 at 406 604 km and the perigee on 21 January at 22:47 at 357 283 km. Because the Full Moon comes only about 15 hours after that perigee, at 357 644 km, it is listed under Supermoons and highlighted on the page.

The daily table starts with 1 January: waning crescent, 33 % lit, moonrise 02:08, moonset 11:39.

How to read the result

  • Each day box shows the date, the lit percentage (top corner), the Moon drawing, any phase, perigee, apogee or supermoon label, and moonrise and moonset at the bottom. A missing time means the Moon does not rise or set on that calendar day.
  • Phase and percentage are for local noon; the exact phase times are in the table and on the day of the phase.
  • The drawing is lit on the right while the Moon waxes, as seen from the northern hemisphere. For places south of the equator it is mirrored.
  • Distances are centre to centre, Earth to Moon.

Tips and common mistakes

  • Use the time zone of the place, not of your computer: moonrise in Sydney printed with a European time zone is useless.
  • "Whole year on one page" in landscape makes a compact wall overview; one month per page leaves room for the rise and set times.
  • The place line is printed in the footer, so a gift calendar can say "Our cabin in Lapland".
  • Labels such as "Full Moon" are printed in the chosen language once the site translations exist; month and weekday names are always localised.
  • Moonrise assumes a flat horizon; behind hills the Moon appears later.

FAQ

What counts as a supermoon?

A full or new Moon within 10 % of the closest end of that month's perigee–apogee range (R. Nolle's definition). In 2027 the Full Moon of 22 January is one of them.

How exact are the times?

Phases and perigee times agree with published tables to within a few minutes; moonrise and moonset follow the U.S. Naval Observatory convention.

Can I print other years?

Yes, any year from 1900 to 2100.

Which paper sizes are available?

A4, A3, US Letter and Tabloid, in portrait or landscape. The PDF uses vector graphics and embedded Noto fonts, so it stays sharp when scaled.
