The codes
Nepali date conversion consists of two parts
A. Data of number of days that occur in each month in each year. This is the reason why all the Nepali date conversion programs have its limitations
B. Algorithm to convert the date from AD to BS or vice versa.
This is explained with the code in VBA (in Excel) below with the required steps.
1. Open MS Excel
2. Open Visual Basic editor (short cut Alt + F11)
3. Insert a class module
4. Rename the class module to Nepali_Calender in Properties window (F4)
5. Paste the code 1 given at the end of this article
6. Insert a Module (normal module not class module!) and Paste the code 2 . It consists of two functions :
a. nepaliToEnglish(y,m,d,formateCode)
b. englishToNepali(y,m,d,formateCode)
where y,m,d=year, month and day and formate code will display the desired output format
Formate code | Formate |
0 | 20671/25 |
1 | 2067-Mangsir-25 |
2 | 2067-Mangsir-25-Saturday |
7. Now close the editor
8. Save your file as *.xlsm (macro enabled)
9. Now you can use two functions made in step 6
10. To make these functions available to all the worksheets
a. save this sheet as add-ins *.xlam format
b. then enable it at Excel Options>Add in>Manage
c. the function will be available as user defined function under Insert functions
11. . In this code the limits are
a. AD 1944-2033
b. BS 2000-2089
c. if date is out of range then output is string "Out of range"
The readymade file is also available. Download NepaliDateConverterAddIn.xlsm now.
