Calendar Core

Framework-agnostic calendar utilities built with the Temporal API. Simple, composable functions for building month, week, and day views.

👉 Documentation

• Built on Temporal API - No Date objects, no moment.js, no date-fns
• Timezone-aware - Native DST handling with IANA timezones
• Type-safe - Full TypeScript with proper Temporal types
• Framework-agnostic - Use with React, Vue, Svelte, or vanilla JS
• Data-agnostic - Works with any data type through accessor pattern

import { buildMonth, createCalendarAccessor, getWeekdays } from '@gobrand/calendar-core';

const accessor = createCalendarAccessor<Event>({
  getDate: (e) => e.date,
});

const month = buildMonth(2025, 1, { weekStartsOn: 1, data: events, accessor });

month.weeks.flat().forEach(day => {
  console.log(day.date.toString(), day.items.length);
});
