More in Dates & Time
An immutable date-time toolkit — arithmetic, start/end of unit, diff & breakdown, comparison, token format/parse and ISO — a tiny date-fns/dayjs with no dependencies. Zero-dependency, isomorphic.
@lacspace/durationA Duration type — parse, build, normalize and do arithmetic on ISO-8601 time spans, calendar-honest about months & years (never silently assumes a 30-day month). Pairs with @lacspace/humanize for display. Zero-dependency, isomorphic.
@lacspace/timezoneAn IANA timezone toolkit built on Intl — DST-correct offsets, wall-clock parts, zoned↔UTC conversion and DST detection, with no bundled tz database so it stays tiny and always current. Zero-dependency, isomorphic.
