How do I print a monthly or yearly moon phase calendar?

Pick a month, choose One month or Whole year, then Download printable PDF. A yearly download contains twelve landscape pages, one per month. The file includes original vector discs, day numbers, approximate illumination and published primary-phase markers. Your browser prepares the file locally.

Can I view 2025, 2026 or another year?

Yes. The month selector accepts January 1900 through December 2100. Choose a month in the year you want, then Whole year for its twelve months. Leap days follow the Gregorian calendar; a year query uses this one working calendar page.

What is included in the daily CSV?

One row per calendar day gives its UT date, approximate phase name and illuminated percentage at 12:00 UT, plus any published USNO primary-phase times on that UT day. One month exports only the selected month; Whole year exports every day of that year.

Why can a daily Full moon illustration differ from the exact full moon marker?

The drawing is sampled at 12:00 UT and uses a broad approximate phase band. The event marker is a published primary-phase time at a specific minute, which can occur before or after noon. A phase band does not mean the exact event happens every day displaying that name.

Does this calendar include astrology, blue moons, moonrise or local visibility?

It lists the four ordinary primary phases and approximate daily illustrations. It does not interpret zodiac signs, identify special blue/super/rare events, predict eclipses or provide location-specific rise/set and visibility. UT event dates can differ from a local calendar date.

Calendar days and principal-phase dates use UT. Daily discs show an approximate interpolation at 12:00 UT. Published new, quarter and full moon times use Universal Time (UT), at minute resolution. Hemisphere only mirrors the drawing.

One Moon, one phase at the same instant. Local calendar dates and viewing angles can differ. The drawing does not predict moonrise, moonset, cloud cover, visibility or the exact tilt at your location. New, quarter and full moon times come from the US Naval Observatory in Universal Time, at minute resolution. Illumination, phase labels and the disc between those events are approximate interpolations. The hemisphere switch is a drawing convention, not a location-specific view.
