dayte

A day-friendly datetime library.

Most business logic thinks in calendar days — invoices, deadlines, bookings, birthdays — not in instants. Existing datetime libraries centre on timestamps and timezones, which makes day-level work awkward.

dayte treats the calendar day as the primary unit. Its design is heavily based on EDTF (Extended Date/Time Format) and ISO 8601-2, giving first-class form to reduced-precision dates (a year, a month), uncertain and approximate dates, seasons, sets, and intervals.

Packages

• Python — dayte on PyPI
• TypeScript — dayte on npm

Pre-release: nothing is published yet. Both packages are under active development.
