Gaurabda: Vaiṣṇava Calendar

A Vaiṣṇava calendar for iPhone, iPad and Apple Watch, calculated the same way as GCAL — the calendar program by Gopalapriya dasa that devotees have trusted for years to plan their fasts and festivals. THE SAME RESULTS AS GCAL 11 The GCAL calculation engine was ported to Swift and checked against the original on hundreds of thousands of values: sunrise, tithi, nakṣatra, Ekādaśī, pāraṇa and festivals match GCal 11 to the second. Time zones and daylight saving, kṣaya and adhika māsas and polar latitudes are all handled. THE DAY AT A GLANCE Tithi and pakṣa with the phase of the Moon, the māsa and the Gaurābda year, festivals, appearance and disappearance days of the ācāryas. Sunrise, noon and sunset, brahma-muhūrta and the windows of the three sandhyās — Gāyatrī, Sāvitrī and Sarasvatī. Nakṣatra, yoga and rāśi at sunrise, and the events of the day to the second. FASTING AND PĀRAṆA Ekādaśī, Mahādvādaśī and appearance-day fasts, with the pāraṇa window for the next morning and the rule it was calculated by. THE MONTH A month grid marked with fasts, pāraṇa and festivals, plus a list of every event in the month. REMINDERS The day before a fast, on the morning of pāraṇa, for festivals, at the start of brahma-muhūrta and of each sandhyā — at the times you choose. SANDHYĀ TIMER Five minutes before each sandhyā a timer appears on the Lock Screen, in the Dynamic Island and on Apple Watch, showing how much time is left to chant. Tap "Done" and it goes away. The timer starts on its own on iOS 26 and later. APPLE WATCH The day on your wrist, plus watch-face complications: the next sandhyā with a time ring, today's sandhyās, brahma-muhūrta. WIDGETS On the Home Screen — the next event and the month; on the Lock Screen — today's sandhyās and brahma-muhūrta. ANYWHERE IN THE WORLD 95,000 cities built in, searchable offline.
