✦ zenith calendar · the vedic astrology almanac
sign changes and planetary turns in one quiet layer of your sky, each at its exact moment.
astrology · vedic is one of the sky almanacs that come with zenith calendar. it holds the sidereal zodiac by the lahiri ayanamsa: the sun and the planets from mercury to pluto entering each sign, and each planet turning retrograde or direct. it holds no moon entries, and no rahu or ketu.
its moments were worked out once, before the app shipped; nothing is worked out on your phone. each one shows on the day it falls where you are, with its exact time on its own page.
sidereal zodiac · by the lahiri ayanamsa, against the fixed stars
the sun entering a sign
the moment the sun crosses into a new sign of the sidereal zodiac.
an all-day entry on the day that moment falls where your phone is, with its exact time on its own page; dated by universal time here.
a planet turning retrograde
the moment a planet turns retrograde, kept for each planet from mercury to pluto.
shown on its day like every moment in the almanac, with its exact time on its own page.
a planet entering a sign
the moment a planet crosses into a new sidereal sign, kept for each planet from mercury to pluto.
shown on its day like every moment in the almanac, with its exact time on its own page.
the sun entering the first sign
the sun's entry into sidereal aries, measured against the fixed stars.
about three weeks after the same entry in the western almanac, because the two zodiacs read the same sky about 24 degrees apart.
zenith calendar draws the year as an orbit round the sun. lit, astrology · vedic puts its moments on their days on that ring, in starlight. its mark is ✦, a four-pointed star, for the fixed stars it is measured against.
each entry is kept as its exact moment and drawn as an all-day entry on the day that moment falls where your phone is, with its exact time on its own page.
vedic and western are two almanacs rather than one with a switch, because they read the same sky about 24 degrees, roughly three weeks of dates, apart. light the one you follow, or both.
astrology · vedic arrives locked, so nothing in it changes by accident. the lock guards your hand, not your eye: tap its chip in the legend to eclipse it (kept, but not drawn) and tap again to shine it. one tap unlocks it, and then it is yours to rename, recolour or add to.
astrology · vedic shares one sky with your own commitments. like every almanac that comes with the app, it never counts toward the almanacs you can make for free, and it lives on your phone: zenith calendar has no server of its own.
✦ zenith calendar · the sky around it
astrology · vedic is a single layer. beneath it is a whole calendar drawn as the sky, your year an orbit round the sun, and every part of it answers your touch.
the sun stands at the centre and the year rings round it, with today's earth riding at today's place, its small moon beside it. tap the ring anywhere else and a faint ghost earth waits on that day.
drag along the ring and the days pass under your finger, the big date and the day's list following as you go. lift, and the day you stopped on stays picked.
tap the small moon beside today's earth and you dive into the week. the moon above shows its phase, named underneath; swipe the dates and each week brings its own.
tap the sun and the ring tips on its edge into a ladder of years. in the week, pull the moon firmly down and the month opens, the moon resting half off its foot.
zenith calendar has no server of its own. tap the gear and switch on "nothing comes in" or "nothing leaves this phone"; lift them, and every almanac is back exactly as it was.
astrology · vedic is waiting in the app, and the rest of the sky comes with it.

Vedic uses the sidereal zodiac by the Lahiri ayanamsa, measured against the fixed stars. Western uses the tropical zodiac, measured from the spring equinox. The two read the same sky about 24 degrees apart, so they are separate almanacs.
Zenith Calendar for Android comes with an almanac called astrology · vedic: the sun and planets entering each sidereal sign, and each planet turning retrograde or direct, drawn on the ring of your year beside your own days. Turning it on costs nothing.
No. It holds the sun and the planets from Mercury to Pluto entering each sign, and each planet's retrograde and direct turns. There are no moon entries, and no Rahu or Ketu.
They were worked out once by the calendar's own astronomy before the app shipped, by the Lahiri ayanamsa, so nothing is worked out on your phone.
