Create business calendars that automatically account for public holidays in any country.

Public Holidays

Business calendars that ignore public holidays produce wrong estimates. A project timeline that counts 20 working days in December will be off by 2-3 days in most countries because of holiday closures. Shipping date calculators, SLA timers, and billing cycles all need accurate working-day counts to function correctly.

The holidays skill provides the raw data needed to build holiday-aware calendars for any country. Feed the holiday dates into your scheduling system, SLA calculator, or project management tool to get accurate working-day counts. No more manual holiday lookups or outdated spreadsheets -- pull fresh data for any country and year programmatically.

This is critical for logistics companies calculating delivery windows, financial services computing settlement dates, HR systems tracking paid time off, and any application where the difference between a holiday and a working day matters for accuracy.
