Frequently Asked Questions

How do I subscribe to holiday calendars in Google Calendar or Outlook?

In Google Calendar, click '+' next to 'Other calendars' and select 'From URL', then paste your webcal:// link. In Microsoft Outlook, select 'Add Calendar' → 'Subscribe from web'. This keeps your holiday feed automatically synchronized with zero manual updates.

What is the difference between downloading an .ics file and subscribing via webcal://?

Downloading an .ics file imports a static one-time snapshot of events into your calendar. Subscribing via webcal:// creates a live URL sync that automatically updates if statutory authorities proclaim in-lieu days or adjust holiday dates.

Can I combine holidays from multiple countries into a single calendar feed?

Yes. The HolidayExplore Composite Feed Builder allows you to check up to 8 countries (such as US, UK, and India) and choose whether to include central bank payment rail closures and stock exchange halts into a single unified .ics file.
