The Astrolendar is a calendar with Zodiac months built around the sky instead of the Gregorian year.

Organized into twelve solar seasons, one per Zodiac sign, each running from the moment the Sun enters that sign to the moment it leaves for the next.

Every day shows its Zodiac degree alongside its familiar Gregorian month and date, and the days of the week are renamed for the seven classical planets: Sun Day, Moon Day, Mars Day, Mercury Day, Jupiter Day, Venus Day, Saturn Day.

On every grid:

• Zodiac degree and Gregorian date, every day
• Moon phases and eclipses, marked and dated
• Every major planetary transit, with exact times
• Available across multiple U.S. time zones
• Available starting with different Zodiac months
