The Smarta day is the civil day on which the Ekadashi tithi is current at Boston sunrise. When Ekadashi began in the dawn window (after arunodaya, ~96 minutes before sunrise) Dashami is treated as still touching the day, and Vaishnava traditions (ISKCON, Gaudiya, many South Indian sampradayas) fast the following day instead — those cases are marked.

Sun and Moon longitudes are computed with Jean Meeus' algorithms (Astronomical Algorithms, ch. 25 and 47); the Moon series used here is accurate to about 0.05°, so tithi boundaries are typically within a few minutes of a full ephemeris — checked against the timed new and full moons of the 2024–2026 eclipses. Sidereal positions use the Lahiri (Chitrapaksha) ayanamsa. Lunar months are amanta and named by the solar ingress that falls inside them; a month with no ingress is adhika. Sunrise uses the NOAA solar-position method with standard refraction. Times are shown in America/New_York including daylight saving. Observance rules are stated per festival above. This is a computed reference, not a temple panchang: for a specific ritual, confirm with your temple, priest or family panchang.
Ghatasthapana (Dashain begins) is Sun, 11 Oct 2026, Maha Ashtami Sun, 18 Oct 2026, Maha Navami Mon, 19 Oct 2026 and Vijaya Dashami (Tika) Tue, 20 Oct 2026 — computed for Boston sunrise (udaya tithi). In Kathmandu the Tika day is Wed, 21 Oct 2026 — the tithi boundary falls between the two sunrises.
Kag Tihar / Dhanteras Fri, 6 Nov 2026, Kukur Tihar / Naraka Chaturdashi Sat, 7 Nov 2026, Lakshmi Puja / Gai Tihar / Diwali Sun, 8 Nov 2026 (the evening the Amavasya covers pradosh), Govardhan / Mha Puja Mon, 9 Nov 2026, Bhai Tika / Bhai Dooj Tue, 10 Nov 2026. Chhath is Sun, 15 Nov 2026.
Sun and Moon positions from Meeus' algorithms (Moon to ~0.05°, so tithi boundaries are typically within a few minutes), Lahiri ayanamsa, amanta lunar months named by the solar ingress inside them (a month with no ingress is adhika). Each festival is placed on the Boston civil day whose sunrise falls inside the tithi (udaya tithi), except Diwali (Amavasya at pradosh), Shivaratri and Janmashtami (tithi covering local midnight) and Sankranti festivals (day of the Sun's sidereal ingress). Tithi start and end times are shown so you can apply your own tradition's rule; confirm with your temple or family panchang for observance-specific practice.
Because Boston sunrise is ten to fifteen hours BEHIND Kathmandu's. When a tithi ends in that gap, the United States keeps the festival a day EARLIER than Nepal or India — in 2026 that happens to Vijaya Dashami (Tika), Bhai Tika and Janmashtami, among others. The Kathmandu date is shown beside each festival where it differs; families who keep the home-country date for calls and tika can simply use that column.
The table gives both: the Smarta day (Ekadashi current at local sunrise) and the Vaishnava day, which moves to the following day when Ekadashi began in the dawn window (after arunodaya, ~96 minutes before sunrise) — the dashami-viddha rule followed by ISKCON, Gaudiya and many South Indian traditions. Most Ekadashis are the same day under both; the exceptions are marked. If your family follows a specific tradition, use its column.
