Almanac Row Calendars

One date, seven calendars. Almanac Row Calendars lays any day out on a quiet almanac page and shows it in Gregorian, Julian, Hebrew, tabular Islamic, Solar Hijri, Ethiopian and Coptic reckonings at once. CONVERT Pick a calendar and step its day, month or year. Every other calendar follows live. Each row shows the date, its month position, day of year and a leap-year mark. A stat strip above the page gives the weekday, ISO week date and Julian Day Number. BETWEEN Count the days between two dates, each entered in any calendar you like, and read the result in days, weeks and a year-month-day span. You can also add or subtract any number of days from a date and see the result in two calendars. EASTER See Easter Sunday by both the Gregorian and Julian reckonings for any year from 326 to 2999, with a Sunday strip and an eight-year table. SYSTEMS AND HOW Learn how each calendar works and how the conversions are made. BUILT TO BE TRUSTED Every calendar converts through the Julian Day Number using arithmetic rules. At start-up the app checks reference dates and sweeps the full supported range; any calendar that fails the check is hidden rather than shown wrong. Tabular Islamic dates can differ by a day from moon-sighting dates, and the app says so.
