Attic Calendar vs Orbit Astro Calendar

Attic Calendar allows you to track the calendar used in ancient Athens, including toggleable date markers for solstices and equinoxes, moon phases (as seen from Athens, Greece), and ancient Greek festivals and related events as recorded by Hellenion. A lock screen widget and home screen widgets are available to help you keep track of the days and festivals at a glance. The calendar is calculated using the following rules: 1. The earliest supported Olympiad and year (Ol. 1.1) is defined as starting in the summer of 776 BCE. 2. For calculation purposes, days start at sunset as they did in ancient Greece, though for display purposes the days can start at midnight via the app's settings. 3. The start of a new month begins when a new moon is more than 20 hours before sunset. In other words, if the new moon was more than 20 hours before sunset, the sunset would start a new month, but if the new moon was less than 20 hours, the moon would be considered to not yet be visible to the naked eye and therefore the month would start the following day. 4. The beginning of a new year started at the beginning of a new month after the summer solstice. 5. In years with 13 months, the extra month has been added after Poseideon as Poseideon II, as was frequently done. Note that historical dates are calculated using the above rules rather than referencing the specific dates used in the past. The Attic calendar was not always consistently modified in ancient Athens. For example, the intercalated 13th month could be inserted at different times in the year and with a different name. These variations are not captured in this app. The HMEPA calendar (used by Hellenion) is also supported now! Special thanks to HMEPA and Hellenion for their contributions to Attic calendar research.

Orbit Astro Calendar is the astrological sky as a calendar. Every Moon phase, every Void Moon, every sign change and station, and every exact aspect appears as an event at its minute, in your own time zone. There are no glyphs to decode: each one is a plain easy-to-read text, like “Mars in Leo square Saturn in Scorpio at 3°14′.” WHAT’S INSIDE • My transits. Add the date, time, and place you were born, and Orbit shows when the current sky meets your birthday sky. Your birth details stay on your phone. • Moon phases to the minute, with the solar and lunar eclipses. • Void Moons, with how long each one lasts. • Ingresses and stations: the Moon and planets entering new signs, turning retrograde, and turning direct. • Aspects: the five major ones between the Sun and Pluto, each spelled out in a plain sentence. • Asteroids, Chiron, the North Node, and Lilith, for those who follow them. • Eight fixed stars: Aldebaran, Regulus, Antares, Fomalhaut, Spica, Sirius, Algol, and Alcyone. • Western or Vedic: the tropical zodiac, or the sidereal (Lahiri). A PLAIN LANGUAGE ASTROLOGY CALENDAR Day, 2-day, week, list, month, and year views, with every kind of event in its own color. Turn any of them on and off. Tap an event to add it to Apple Calendar, or to be reminded the moment it happens. Put the Moon’s sign on your Lock Screen. Light and dark, on iPhone and iPad. HOW IT’S CALCULATED Positions come from NASA JPL’s DE440 planetary ephemeris, the same data the Jet Propulsion Laboratory uses to navigate spacecraft; Chiron and the asteroids from JPL Horizons. Everything is worked out on your phone. It covers 2026 through 2029 and will be extended each year. PRIVATE BY DESIGN No account, no tracking, no ads. Nothing you enter leaves your phone.
