Class: CarbonInterval

Defined in: packages/core/src/datetime/CarbonInterval.ts:44

An immutable, calendar-aware duration backed by Temporal.Duration; every modifier returns a new instance. Build durations fluently, do arithmetic on them, apply them to a Carbon, and render them for humans or as ISO 8601.

Example

import { Carbon, CarbonInterval } from "@zerotal/core/carbon";

const span = CarbonInterval.days(1).andHours(2).andMinutes(30);
span.forHumans();          // "1 day 2 hours 30 minutes"
span.toISO();              // "P1DT2H30M"
Carbon.now().add(span);    // apply to a date

CarbonInterval.fromISO("PT90M").cascade(); // → 1 hour 30 minutes
