Report by Nepal’s fiscal year

>>> from sambat.fiscal import FiscalYear
>>> fy = FiscalYear.of(date(2082, 10, 5))
>>> fy, fy.label_ne
(FiscalYear(2082), '२०८२/८३')

(sambat.date(2082, 4, 1), sambat.date(2083, 3, 32))

Fiscal years beyond the published calendar

A fiscal year that ends after sambat.MAXYEAR can be created, and its earlier parts queried. Boundaries that fall in an unpublished BS year raise ValueError:

>>> current = FiscalYear(2083)
>>> current.quarter(1)
Period(sambat.date(2083, 4, 1), sambat.date(2083, 6, 31))
>>> current.end
Traceback (most recent call last):
    ...
ValueError: year 2084 is out of range; sambat supports BS 1975..2083 (later years had no officially published calendar when this version of sambat was released; upgrading sambat may add them)

Organisations with a different financial year can pass start_month, for example FiscalYear.of(d, start_month=1) for a Baishakh–Chaitra year.
