Frequently Asked Questions
How does the BS to AD date converter work?
It counts calendar days using bundled month-length data for BS 1975–2099. A fixed difference in years is not sufficient because the month lengths vary.
What is the supported date range?
The page displays the exact supported endpoints above the inputs. Dates outside that range are rejected rather than estimated. Future dates depend on the bundled calendar table; compare important dates with the relevant published calendar.
Does the calendar show festivals or holidays?
This calendar shows dates and weekdays only. It does not calculate festivals, lunar observances or public holidays.
Is my birth date uploaded or saved?
No. The conversion runs in your browser using calendar data served with this page. Kalika does not upload or save entered dates.
Which timezone does Today in Nepal use?
The shortcut takes today’s date in Asia/Kathmandu. Manually entered dates are calendar dates, so converting them does not shift the result based on your device’s timezone.

Convert a Nepali birth date without guessing the year offset
Choose BS → AD, select the year, month and day from your record, then press Convert date. Copy the Gregorian date shown in the result only after checking the source date. Adding or subtracting a fixed number of years cannot account for varying BS month lengths.
A date you can check
BS 1975-01-01 converts to AD 1918-04-13, the first supported date in the bundled table. Converting that AD date back should return the same BS date. Month 1 is Baisakh; match the month name as well as its number.
Before using a result on an official form
Confirm whether the form expects AD or BS and check its date format. The result uses year-month-day, so AD 1918-04-13 means 13 April 1918. Compare important dates with the relevant official record or published calendar; this tool does not certify a date or determine someone’s age.
