Store description excerpt

The National Calendar of India, on your phone. Adopted in 1957 on the recommendation of the Calendar Reform Committee chaired by Meghnad Saha, the Indian National Calendar (Saka Samvat) is the official civil calendar of India. It is used alongside the Gregorian calendar by the Gazette of India, in news broadcasts by All India Radio, and in calendars and communications issued by the Government of India. This app shows you today's National date, converts any date in either direction, and explains how the calendar actually works. WHAT YOU CAN DO • See today at a glance — today's National date (e.g. 23 Saur Ashadha 1948) together with the Gregorian date. • Read the month either way — view a full month in the National calendar with Gregorian dates inside each day, or flip to a Gregorian month with the National dates inside. Nothing to convert in your head. • Convert any date — pick a Date, Maah and Year (or a Gregorian date) and get the matching date instantly. Step day by day with the arrows, or jump back to Today. • Understand the year — an interactive orbit diagram shows where the Earth is in its journey around the Sun: the twelve months, the six Ritus, both Ayans, and the solstices and equinoxes. Tap any month to jump to it. • Check the era — Shakabd and Yugabd, plus the current Ritu and Ayan. • Use Vedic month names — switch to Madhu, Madhav, Shukra and the rest with one toggle. • Label the days that matter — save a label on any date and get a reminder the day before, so you never miss an anniversary or observance. • Add a widget — put today's National date on your home screen, or a full month view. • National days are marked — Republic Day, Shaheed Diwas, Ambedkar Jayanti, Independence Day and Gandhi Jayanti. • Read the background — a built-in explainer covers the leap-year rule, the month lengths, and why they are what they are. IN YOUR LANGUAGE Available in English, हिंदी and मराठी. Pick a language inside the app, or let it follow your phone's setting. HOW THE CALENDAR WORKS • It is a solar calendar based on the Sayana system, which tracks the movement of the Vernal Equinox. It is not a Panchang — the traditional luni-solar calendar shares the month names but is a different system. • The year is 365.2422 days long, equal to a tropical year. • The year begins at the Vernal Equinox, 22 March in the Gregorian calendar. • It uses the Saka era. Subtract 78 from the Gregorian year to get the Saka year. • Chaitra has 30 days (31 in a leap year). Vaisakha, Jyeshtha, Ashadha, Shravana and Bhadra have 31 days. Ashwin, Kartika, Agrahayana, Pausha, Magha and Phalguna have 30 days. The uneven lengths follow Kepler's law — the Earth moves more slowly in the first half of the year. • The calendar began on 22 March 1957, as Saur Chaitra 01, 1879. Made by Alok Mandavgane.
