About Nepal Sambat & Panchanga Calculation
An era begun in 879 CE · ई. सं. ८७९ पाखें न्ह्याःगु संवत्
Nepal Sambat is the indigenous lunisolar era of Nepal, counted from 879 CE and carried above all by the Newar calendar of the Kathmandu Valley. The year opens on Kachhalā Thwa Pāru, the day of Mha Pūjā, when the household turns and worships its own selves — and closes twelve lunar months later.
A day here is a tithi, not a rotation · थन न्हि धयागु 'तिथि' खः
The NS date of any day is the tithi in effect at sunrise: one thirtieth of a lunation, measured off every 12° of elongation between Moon and Sun. Because a tithi runs shorter or longer than a solar day, a number sometimes repeats and sometimes vanishes — visible in the grid above, and correct rather than broken.
Lunar & solar alignment · चन्द्रमास व सौर्यमासया समन्वय
Solar calendars begin months at sankranti, when the Sun enters a sidereal sign, and count plain sunrise-to-sunrise days. Nepal Sambat is lunisolar — tracking both lunar tithis and solar seasons so that every festival stays anchored to its natural season.

8. What is Analā (the 13th leap month)?
Because 12 lunar months total ~354 days, a 13th leap month called Analā (अनला) comes every 4th year to align lunar festivals with the solar seasons.
9. Why is tithi calculated at sunrise in Kathmandu?
In the Newar Panchanga tradition, the civil day takes the tithi active at sunrise over Kaal Bhairab, Kathmandu, governing the full day's observances.
