lunar · the hijri months, by a published calendar
1 ramadan
the first day of the month of fasting, one of the five pillars of islam. from dawn to sunset there is no food, drink or intimacy, for every adult muslim who is able.
the day starts with suhur, a meal before dawn, and the fast is broken at sunset with dates or water, then iftar with family and neighbours. at night the mosques fill for tarawih prayer, and many read the whole quran over the month and give generously in charity.
the festival of breaking the fast
1 shawwal
the festival of breaking the fast, on the first of shawwal, when ramadan ends.
each household gives zakat al-fitr before the prayer; people put on their best clothes, pray the eid prayer in congregation, then greet one another with "eid mubarak", visit family and share sweets. it is ramazan bayramı in türkiye, lebaran in indonesia and hari raya aidilfitri in malaysia.
9 dhu al-hijjah
the heart of the hajj. the prophet ﷺ said "the hajj is arafah", and there is no day on which allah frees more of his servants from the fire.
pilgrims stand at arafat from noon until sunset in prayer, tears and du'a. those not on hajj fast the day, and from its dawn many begin the takbir after every prayer.
the festival of sacrifice
10 dhu al-hijjah
the festival of sacrifice, the greater eid. it honours the prophet ibrahim's readiness to give what he loved most to allah.
the eid prayer in the morning, then those who are able sacrifice a sheep, goat, cow or camel, and the meat is shared with family, neighbours and the poor. it is kurban bayramı in türkiye, tabaski in west africa and hari raya haji in south-east asia.
zenith calendar draws the year as an orbit round the sun. lit, sunni puts its days on their dates on that ring, in mint. its mark is ☪, the star and crescent.
each day carries three short paragraphs in its notes: what it is, where it comes from as its own tradition tells it, and how it is kept.
sunni arrives locked, so nothing in it changes by accident. the lock guards your hand, not your eye: you can still read it, shine it or eclipse it. one tap unlocks it, and then it is yours to rename, recolour or add to.
tap its chip in the legend to eclipse it (kept, but not drawn) and tap again to bring it back. nothing is deleted either way.
sunni 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
sunni 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.
sunni is waiting in the app, and the rest of the sky comes with it.

Sunni holds the Sunni days of the Hijri year by a published calendar. Shia holds a twelver (Ja'fari) calendar by its advance reckoning, with the births and martyrdoms of the Imams. They are separate almanacs, so you light the one you keep.
