English Date: Anno Domini (AD)  and Nepali Date: Bikram Sambat (BS) Date Converter. Converting AD to BS is not a rocket science, all it depends on data mapping. Here, I have created Table DateLog which holds English Date as well as Nepali Date. Conversion Logic reside in this scalar function [dbo].[ufn_GetBikramSambatDate].

答案 1 :(得分：1)

尼泊尔日历以Bikram Sambat为基础，分别为56岁和8岁 比A.D.提前几个月，Bikram Sambat日历开始了 在公元前57年国王Bikramaditya在印度。

这些日期之间的差异大致为57年，8个月和16天。要获得BS日期，您需要在AD日期中添加57年，8个月和16天。但主要问题是可能存在+/- 3天的差异

我假设56岁零8个月

SELECT GETDATE() AS 'English Date',
   DATEADD(MONTH,8,DATEADD(YEAR,56,GETDATE())) AS 'Nepali date'

有关DATEADD
