What this page gives

Vikram Samvat and Shaka Samvat start the year on Chaitra Shukla Pratipada. Many families in Gujarat start it on Kartika Shukla Pratipada, after Diwali, instead.

The samvatsara is one of 60 year names. The Ugadi count used in South India and the count in North Indian panchangs give different names.

The ayana is the Sun's half-year. Uttarayana runs from Makara Sankranti to Karka Sankranti here; some panchangs count it from the solstices.

The ritu is one of six seasons. Here it follows the lunar month; some panchangs follow the Sun.

Month, paksha, tithi and nakshatra are read at sunrise in your city, so they can differ from a printed calendar.

This page gives the calendar values. Your family priest's wording for the sankalpa comes first.
