Zanshin Calendar

Tibetan and Japanese calendars with almanac readings, and a meditation timer
New in version 3.0
Reckonings: the birth, the marriage match, a relative who has died, the thirty starting points, the thirteen circles with the golden turtle, the present moment, and building a house in your year of age. Two home-screen widgets. A morning notice. Maroon and Sepia themes. Large fonts, and two columns in landscape. Works you pin come first, each with a glyph of its own. Every almanac row opens, its reading in one shape.
Zanshin Calendar shows one day at a time in the Tibetan calendar or in the old Japanese calendar (旧暦), with the almanac readings that belong to that day, and sunrise, solar noon and sunset for your place. A meditation timer and a mindfulness bell come with it.

Tibetan calendar, Phugpa (ཕུག་པ, phug pa)

  • Lunar day, month and year, with skipped and doubled days and leap months

  • Festivals: Losar (ལོ་གསར, lo gsar), Chötrul Düchen (ཆོ་འཕྲུལ་དུས་ཆེན, cho 'phrul dus chen), Saga Dawa Düchen (ས་ག་ཟླ་བའི་དུས་ཆེན, sa ga zla ba'i dus chen), Chökhor Düchen (ཆོས་འཁོར་དུས་ཆེན, chos 'khor dus chen), Lhabab Düchen (ལྷ་བབས་དུས་ཆེན, lha babs dus chen) and others

  • Monthly observances on the 8th, 10th, 15th, 25th and 30th

  • Lunar mansion, yoga and karaṇa, the element pair of weekday and mansion, the lunar-day animal, trigram and number

  • What changes within the day, as the almanac of the White Beryl (བཻཌཱུར་དཀར་པོ, bai DUr dkar po) writes it: a second mansion, a skipped yoga and the span of Viṣṭi, each with its time

  • The date's mewa (སྨེ་བ, sme ba), with what the activity lists name it good or bad for, and the twelve links (རྟེན་འབྲེལ, rten 'brel) counted from the month's middle term, each day's link with its works, directions and remedy

  • The hundred feet (རྐང་བརྒྱ, rkang brgya): the fangs of the moon, the sun, the five planets and Rāhu on your birth mansion, and the spear and great spear on the moon's mansion

  • What the almanac writes at the head of each month: whether it is long or short, the planet that rises, the black months, the seven days of the sage (དྲང་སྲོང, drang srong) and of the pig, and the comet its count marks

  • Lunar and solar eclipses as the almanac reckons them, by the karaṇa reckoning (བྱེད་རྩིས, byed rtsis) of the Kālacakra (དུས་འཁོར, dus 'khor), on their day, with the merit they multiply

  • The readings of the lunar mansion, date, weekday, yoga, karaṇa and trigram, the special days, Rāhu's course, the earth lords and the direction of the astrologer spirit (བླ་མཁྱེན, bla mkhyen)

  • A day in brief, weighed as the texts rank their factors: the hours above the day, what the activity lists name good or to avoid, today as the present hour decides it, the day's tone and the one factor that decides it

  • Choose a day: the best days for a work over one to twelve months, ranked as the texts weigh them, with its good hours in each month

  • The works you pin, first on the page, each as the day weighs it, and the haircut beside them with its good and bad days and hours; personal days for your birth year

  • Health: what falling ill today means by the date, the weekday, the link and the goddess of the day; where the la, the life-spirit (བླ, bla), sits today and through the day; the day's mansion for your element and the medical works of the day; and the humours and seasons of the Four Tantras (རྒྱུད་བཞི, rgyud bzhi) of medicine; each element's illness, where it lies, its door and its signs. The readings of the tradition, not medical advice

  • A round dial of the hours: the combination period of each hour, Jupiter's nectar periods, the earth lords of the hour, the black hours, what each hour is good for, the four rough times of the sun and the works an hour turns against the day

  • The four aspects of the year (vitality, body, destiny, luck) and, for your birth year, the personal mansions and the white and black pebbles of the year, month, day and each hour

  • Reckonings, a section of their own: your year of age, year by year, by the elemental divination of the White Beryl: the mewa (སྨེ་བ, sme ba), trigram (སྤར་ཁ, spar kha) and progressed sign (ལོག་མེན, log men) of the year, what matters most for you, its twenty-four pebbles with their predictions, the stage of each aspect's energy, and the obstacle years, each with its reading and its remedies, and the year read together, its obstacles graded and its remedies gathered;
