BSDate is a datetime.date for Bikram Sambat. Same constructors, accessors, arithmetic, ordering. strftime tokens are BS-aware.

from datetime import date
from bscal import BSDate, bs_to_ad, ad_to_bs

BSDate.today()
BSDate.fromisoformat("2081-01-01")
BSDate.from_ad(date(2024, 4, 13)).to_ad()

bs_to_ad(2081, 1, 1)         # (y, m, d) -> date
ad_to_bs(date(2024, 4, 13))  # date -> (y, m, d)

bscal.cal is the stdlib calendar for BS: isleap, leapdays, weekday, monthrange, month_name, month_abbr, and a BSCalendar (subclass of calendar.TextCalendar).
