The dated edition

You Have The System. You Don't Have The Year.

Thirteen months of twenty-eight days, dated for 2026 and 2027. Sixty-five pages. Every moon marked on the night it actually rises.

$7 — instant download

A calendar that works in any year can't tell you which day is Day 1. It can't tell you when the moon is full, or which of your thirteen months holds it. It can't show you how far the Gregorian week has slipped out of phase this year, or what it will be next year. For that you need the dates, and the dates have to be computed.

So we computed them.

Calendar page comparing twenty-one years of drifting Gregorian January first weekdays with a fixed calendar — Twenty-one years of January 1. One calendar wanders. One does not.
