About the accuracy. Calculated from the positions of the Sun and Moon (Lahiri ayanamsa, drik method) for the selected city. Times may differ by a few minutes from printed panchangams, and some festival dates may differ by a day depending on the tradition and local sunrise. For ceremonies, please confirm with your priest.

For reference; confirm with your priest. Samvatsara, ayana, ritu, month, paksha, tithi, weekday and nakshatra come from the calculation for the selected day and city. The place lines follow the selected city; the Bay Area form is the default.
How this calendar is calculated
- Place and time: each city preset has its own coordinates and time zone (with daylight saving). A day is reckoned from that city's local sunrise (upper limb of the Sun, standard refraction). Printed calendars often use the centre of the Sun's disc without refraction, which puts sunrise about 3–4 minutes later.
- Tithi: the Moon–Sun elongation (apparent longitudes) divided by 12°. Boundary times agreed with an independent Swiss-Ephemeris based panchang to within about one minute in our checks.
- Nakshatra, yoga: sidereal longitudes with the Lahiri (Chitrapaksha) ayanamsa, 24.22° in 2026. The nakshatra is the Moon's 13°20′ division; yoga uses the Sun + Moon sum.
- Month and year: amanta (new moon to new moon) lunar months named by the Sun's sign at the new moon; a month without a sankranti is shown as Adhika (Adhika Jyeshtha 2026). The 60-year samvatsara changes at Ugadi. Ayana follows the Sun's sidereal longitude; ritu follows the lunar month (Vasanta = Chaitra–Vaishakha).
- Moon icon: illuminated fraction from the Sun–Moon angle at sunrise; waxing (shukla) is lit on the right as seen from the northern hemisphere.
- Festivals: placed by the usual tithi rules (sunrise, midday, afternoon, evening or midnight, and moonrise for Sankashti) using the selected city's sunrise. When a tithi spans two days, temples and almanacs sometimes choose differently, and a US date can differ by a day from India.
- Sankalpam wording: the Bay Area / North-America form follows HinduPad; Anbil Ramaswamy, Hinduism Rediscovered, ch. 21; natarajank.com. The Sanskrit and Telugu spellings of place names (California, San Francisco Bay Area, other states and cities) are phonetic and have not been checked by a scholar; the optional extra lines some priests add (Pacific Ocean, Pushkara kshetra, Rocky Mountains) are not included.
- Not included: eclipses, Rahu kalam and other muhurta timings, Vaishnava Ekadashi days other than the simple cases marked in the list, and festival rules beyond those listed here.
