Moon Calendar Plus: Every Phase, Every Day, Wherever You Are Follow the moon through the month, plan by the light, and read each day in your own calendar. Moon Calendar Plus brings the lunar cycle, precise rise and set times, eclipse forecasts, and a full Hindu panchanga into one clean, fast app. Free to use. One small purchase unlocks everything. No subscription. THE MOON, AT A GLANCE • Month calendar drawing every phase, waxing and waning, full and new • Today's phase with illumination percentage, moon age, and direction • Moonrise, moonset, sunrise, and sunset for any date and any location • Solar and lunar eclipse forecasts, including visibility from where you are • Live moon position with elevation, azimuth, and a 3D compass • Yearly chart of full and new moons, the long view in a single screen • Jump to any year from 2000 to 2040 with a single tap YOUR CALENDAR, BESIDE THE GREGORIAN ONE Show a second date in every cell, written in its own script: • Tamil and Malayalam, reckoned by the true sankranti • Telugu, Kannada, Marathi, and Gujarati amanta months • The Hindu tithi, with paksha • Hebrew, Islamic, Buddhist, Japanese, and Chinese STAR SIGNS, WESTERN AND VEDIC The sign the Moon is in appears under each day of the month. Under the date you get the day's reading: the nakshatra and the rashi, in English, Hindi, Marathi, Gujarati, Tamil, Telugu, Kannada, or Malayalam. Tap it for the whole day. The Vedic reading gives every star the Moon passes and when it changes, the tithi, yoga, and karana, sunrise and moonrise, and the windows an almanac is kept for: Rahu Kalam, Yamagandam, Gulika Kalam, and Abhijit Muhurta. The Western reading gives the Moon's placement and degree, the ascendant and midheaven, the current lunation and the next phase, and the void-of-course Moon. FOR NIGHT AND LANDSCAPE PHOTOGRAPHERS Plan blue hour, golden hour, and full-moon shoots down to the minute. Scrub the date, switch to the location you are shooting from, and see exactly when the light and the moon will land. FOR ASTRONOMERS AND STARGAZERS Find dark-sky windows around the new moon, time eclipses to your coordinates, and track the next supermoon, blood moon, or harvest moon with rise and set data computed for your exact position. FOR GARDENERS, ANGLERS, AND LUNAR PLANNERS Plant by the moon, schedule trips on the right phase, or align routines and observances with the cycle. Every phase, every day, in one place. FOR TRAVELERS Save your home, your destination, and everywhere in between. Times adjust automatically for the location you are viewing, with full time zone and daylight saving handling. No math, no guesswork. WIDGETS AND IPAD Home Screen and Lock Screen widgets keep the moon one glance away. On iPad the calendar, the compass, and the daily reading share the screen, in either orientation. BUILT TO BE EXACT Positions come from standard astronomical algorithms, with the Lahiri ayanamsa for sidereal work. Sunrise, tithi, and nakshatra are computed for your own coordinates, the way a local almanac reckons them, not copied from a fixed table. Download Moon Calendar Plus and start planning by moonlight.
