✦ zenith calendar · the buddhist (vietnam) almanac
the vietnamese lunar year's buddhist days in one quiet layer of your sky, each one explained in its own tradition's words.
buddhist (vietnam) is one of the holiday almanacs that come with zenith calendar. it holds the great days of the vietnam buddhist sangha, by the vietnamese lunar calendar, as the sangha fixes them each year in its circulars.
each day is copied as the circulars give it, not worked out on your phone, and a year the sangha has not yet announced shows nothing rather than a guessed day. tap a day and read three short paragraphs: what it is, where it comes from, and how it is kept.
lunar · the vietnamese lunar months, as the sangha fixes them each year
rằm tháng tư, the full moon of the 4th lunar month
the great day of the buddha's birth, kept by the vietnam buddhist sangha a week later than the chinese day.
temples and homes hang the buddhist flag and lanterns, and people bathe an image of the infant buddha with three ladles of water: to cut off evil, to do good, and to free all beings. many places add flower-float processions and floating flower lanterns (hoa đăng).
the festival of filial gratitude
rằm tháng bảy, the full moon of the 7th lunar month
a day to repay the kindness of mother and father, living and passed, and of ancestors. the sangha keeps it through the whole seventh month, with the main ceremony on the fifteenth.
at the temple a rose is pinned to each person's shirt, red for those whose mother is living and white for those whose mother has passed. people chant the vu lan sutra, pray for the departed, and above all go home to care for their parents.
zenith calendar draws the year as an orbit round the sun. lit, buddhist (vietnam) puts its days on their dates on that ring, in lilac, the colour every buddhist reckoning wears. its mark is ❁.
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.
buddhist (vietnam) 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.
buddhist (vietnam) 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
buddhist (vietnam) 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.
buddhist (vietnam) is waiting in the app, and the rest of the sky comes with it.
