BS to AD Date Converter

Bikram Sambat counts years from an earlier starting point, traditionally linked to King Vikramaditya around 57 BCE. Its new year (Baishakh 1) falls in mid-April, so BS is 57 years ahead of AD from mid-April to December and 56 years ahead from January to mid-April.

Each date is converted day by day with KhataIN's BS calendar table, which records the length of every month in each supported year and is checked against published Nepali calendars. Month lengths for years far in the future can still be revised once they are officially published.

No. Bikram Sambat months follow the sun’s movement through the zodiac, so they are 29 to 32 days long, and the same month can have a different length from one year to the next.

It is a dependable reference for everyday use. For legal, government or banking records, confirm the date against the original document or the issuing office.

Choose BS → AD, enter the year, month and day exactly as written on the Nepali document (citizenship, birth certificate or school certificate), and use the AD date shown. Foreign forms usually want the AD date; keep the BS date as it appears on the original document.

They share the name and the year count, but not the day-to-day dates. Nepal's Bikram Sambat is a solar calendar whose months start when the sun enters each zodiac sign, with the year starting in mid-April. Vikram Samvat as used in India is lunisolar: months follow the moon, and the year starts on different days in different regions. This converter uses Nepal's official Bikram Sambat.
