नेBuilt with care.
Built with care.
Clear about the details.
A useful calendar library starts with knowing exactly what its data covers.
A real, finite calendar.
BS 1975–2083, backed by a versioned month-length table. Dates beyond the table throw instead of guessing.
Calendar provenanceNepal time, correctly.
IANA timezone rules handle modern UTC+05:45 and Nepal’s historical offsets. Civil dates stay separate from instants.
Sources before assumptions.
Holidays carry sources and eligibility scopes. Tithi accepts supplied longitudes or sourced intervals; a daily almanac isn’t bundled.
Data coverageYour next build.
A little more Nepali.
Open source. Typed. Ready to make it yours.
