Calendars of traditions

Every tradition keeps its own year: its festivals, its holy persons, its fasts and how they are broken. In JyotiSoft a tradition's calendar is a profile you connect: its dates for your city, a short story of each day and reminders before each fast. Two are open: the Gaudiya Vaishnava calendar of ISKCON and the Hindu (Smarta) calendar; more will follow, each only from its own authoritative calendar.

ISKCON (Gaudiya Vaishnava)

Connect the ISKCON profile: the dates and the parana for your city, a story of every festival and acharya, and reminders the evening before a fast, on its morning and when the parana window opens.

Hindu (Smarta)

Connect the Smarta profile: the dates and puja times for your city, the Smarta Ekadashi with its parana, Pradosh, Sankashti and Masik Shivaratri, and reminders the evening before a fast, on its morning and when the parana opens.

ISKCON (Gaudiya Vaishnava)

The profile gathers the whole Vaishnava year in one place. Our engine computes the dates by the rules of GCal, the calendar ISKCON keeps, and we check them against the published calendar. For each day you see what is celebrated, who is remembered and how the day is fasted: till noon, till sunset, till moonrise, till midnight, or the full Ekadashi fast. The parana (break-fast) time follows the sunrise in your city. Every festival and acharya has a short note and a longer story with its sources. In the profile settings choose which events to show and when to be reminded; the profile can be on together with others.

Hindu (Smarta)

The profile gathers the Hindu year in one place. The engine picks the date of each festival and vrata by its classical rule: which tithi must hold at which time of day — sunrise, noon, after sunset or midnight; disputed cases follow the Dharmasindhu and the Nirnayasindhu. We check the dates against Drik Panchang for several cities and years. For each day you see what is celebrated, when the puja is and when to break the fast, timed by sunrise and sunset in your city. In the settings choose which vratas to show and when to be reminded; the profile can be connected together with ISKCON and others.

Questions

Can I follow two calendars at once?
Yes. Several profiles can be on together, and each has its own settings: which kinds of days to show, when to be reminded and the quiet hours.
Where do the dates come from?
From the calendar engine of JyotiSoft, by each tradition's own rules, checked against that tradition's published calendar.
Why do the dates differ from city to city?
A Vaishnava day is decided by the sunrise and the dawn of the place, so a fast can fall a day apart in two cities. The table is for Mayapur; the app gives your city's dates.
What does “fast till noon” mean?
On the appearance days of Lord Balarama, Srimati Radharani, Sri Nityananda and other great Vaishnavas the calendar asks for a fast until midday, then a feast. When such a day falls right after Ekadashi, the fast is kept on the Ekadashi and the day itself is the feast, exactly as the ISKCON calendar marks it.
Is the Ekadashi fast safe for everyone?
The fast is kept by one's strength. Strict forms (without water) are not advised for people with health conditions, pregnant women and children; decide with a doctor.
Why does the Smarta Ekadashi sometimes differ from the ISKCON one?
The Smarta rule looks at the tithi at sunrise; the Vaishnava rule of ISKCON also looks at the dawn before it and moves the fast when the tenth day touches it. On four to seven days a year the two fall a day apart. If you connect both profiles, the app shows both.
