Solar Nepal Sambat

 

 

A solar version of Nepal Sambat began from N.S. 1141 Kachhala 1 which co-incided with 20 October 2020. Colloquially in Nepal Bhasa, it is called Nhilyaa kathan yaa nepal sambat [Prachalit Nepal Script: 𑐣𑑂𑐴𑐶𑐮𑑂𑐫𑐵𑑅 𑐎𑐠𑑄𑐫𑐵 𑐣𑐾𑐥𑐵𑐮 𑐳𑐩𑑂𑐧𑐟, Devanagari script : न्हिल्याः कथंया नेपाल सम्बत] which means ‘Nepal Sambat in accordance to date system’.

 

The solar Nepal Sambat is based on earth’s revolution around sun. It has 365 days every year, and 366 on leap years.

Months

There are twelve months in Nepal Sambat. They are as follows:-

Days per month

The first five months Kachhalā, Thinlā, Ponhelā, Sillā and Chillā have 30 days per month. The sixth month Chaulā has 29 days every year and 30 days every leap year. The rest six months Bachhalā, Tachhalā, Dillā, Gunlā, Yanlā and Kaulā have 31 days per month.

Leap Year

The concept of leap year exists across various solar calendars. Since Nepal Sambat has 365 days a year, and the earth takes approximately 365.25 days to complete a revolution around the sun – we loose 0.25 days every year. This means the calendar slowly drifts away from the seasons and actual time. Therefore, to prevent this from happening, the concept of leap year exists.

 

On leap years, one day is added in the year to make it 366 days. The extra day added is the leap day and tansa din [Prachalit Nepal Script: 𑐟𑑃𑐳𑐵 𑐡𑐶𑑄, Devanagari script : तँसा दिं] in Nepal Bhasa. The sixth month Chaulā which has 29 days on regular years, will have one extra day – making it 30 days on leap years.

 

Leap years come approximately every four years. The exact maths to calculate leap year is as follows:
1. Add 880 to the given number of year
2. If the number is evenly divisible by 4 – Go to step number 2, otherwise it isn’t a leap year.
2. If the number is also evenly divisible by 100 – Go to step number 3, otherwise it is a leap year.
3. If the number is also evenly divisible by 400 – It is a leap year, otherwise not.

 

The leap years in Nepal Sambat for next hundred years are 1144, 1148, 1152, 1156, 1160, 1164, 1168, 1172, 1176, 1180, 1184, 1188, 1192, 1196, 1204, 1208, 1212, 1216, 1220, 1224, 1228, 1232, 1236, 1240.

New Year

The Solar New Year of Nepal Sambat falls on it’s first day Kachhala 1, which coincides with October 20 in Gregorian calendar.

 

Nepal Sambat itself began on 20 October 879 A.D., therefore 20 October 2020 was taken as a commencement point for the Solar Nepal Sambat 1141.

Century

Century means ‘a hundred years’. It is called sadi [Prachalit Nepal Script: 𑐳𑐡𑐶, Devanagari script : सदि]. The term in Nepal Bhasa derives from sacchi dan deegu [Prachalit Nepal Script: 𑐳𑐔𑑂𑐕𑐶 𑐡𑑃 𑐡𑐶𑐂𑐐𑐸, Devanagari script : सच्छि दँ दिइगु] which means ‘when hundred years resides’.

 

Since Nepal Sambat started from the year one (N.S. 1) – a century is from one to hundred. In the year 1141, we are in the 12th century of Nepal Sambat. The 12th century began from N.S. 1101 and will end in the year N.S. 1200.
