How the Bikram Sambat calendar works
A few facts that explain why a converter needs a table, and why the day select changes with the month.
- The year begins on 1 Baishakh, in mid-April: 1 Baishakh 2083 is 14 April 2026.
- Twelve months of 29 to 32 days each. Their lengths are set by observation and published for each year, so there is no formula; a converter carries a table.
- The fiscal year starts on 1 Shrawan: 2083/84 runs from 17 July 2026 to 16 July 2027. The IRD writes it 2083.084.
- Monthly returns are due within 25 days of the end of a Bikram Sambat month, so a month's deadline is the 25th of the next month.
- This page's table runs from 1 Baishakh 1975 (13 April 1918) to the end of 2100 (12 April 2044) and is the one BRAccount's documents are dated with.

Nepali calendar questions
How do I convert a Bikram Sambat date to AD?
Count the days from a known anchor through the published month lengths. The BS calendar has no formula: each month is 29 to 32 days by observation, so a converter needs a table of every year's month lengths. This page uses the table BRAccount's books use, 1975 to 2100 BS (13 April 1918 to 12 April 2044), checked day by day.
What is the Nepali fiscal year?
It runs from 1 Shrawan to the last day of Asar. Fiscal year 2083/84 is 1 Shrawan 2083 to 32 Asar 2084, that is 17 July 2026 to 16 July 2027. BRAccount writes it as 2083.084, the IRD's form.
When does the Nepali new year 2083 start?
On 1 Baishakh 2083, 14 April 2026. Baishakh is the first month of the Bikram Sambat year; Shrawan is the first month of the fiscal year.
Does Bikram Sambat have leap years?
Not in the Gregorian sense. The year's length is set by its twelve months, each 29 to 32 days as published, so a BS year is 365 or 366 days and the difference sits inside the months rather than in a leap day.
How many days does Asar 2084 have?
32: the fiscal year 2083/84 ends on 32 Asar 2084, 16 July 2027. Month lengths differ from year to year, which is why the day select on this page changes with the month.
Why does the IRD deadline show on the result?
Because the monthly VAT, TDS and excise returns are due within 25 days of the end of each Bikram Sambat month, so the deadline for a month is the 25th of the next month. The tax calendar lists every deadline of the year.
Which calendar does BRAccount use?
This one. Every document in BRAccount carries both the Bikram Sambat and the AD date and the Nepali fiscal year, from the same table as this page, so the bill, the sales book and the return agree on the month.
Books that keep both dates on their own
Every invoice, payment and report in BRAccount carries the Bikram Sambat and the AD date and the Nepali fiscal year, so nothing is converted by hand.
