Add sport schedules or other special holidays and events to your Calendar

I’ve already added the Holidays to Outlook but I was wondering if I could also easily add other special days and sport schedules to my Calendar.

For instance, I’d like to add the moon phases, the Formula 1 calendar and a countdown to the end of the year.

Can I do this?

Add Sports Calendar buttonFor a lot of unofficial holidays, sport schedules and other things to add to your Calendar, there usually is a (free) Web Calendar service available with all the days and info you want.

The benefit of using a Web Calendar is that it automatically gets updated with new days, new information or in case of sports events, the results of the game, match or race.

Outlook, and Outlook on the Web (OWA) all offer support to subscribe to these Web Calendars.

When you are using an account or are an Office 365 Exchange Online subscriber, then there is also already a big catalog of “Interesting Calendars” which you can add as a Web Calendar.

Calendar websites

  • iCalShare
    This site is a bit more community driven so people can create, upload and share calendars of their own. This results in over 3500 calendars to choose from. You can search for a calendar or browse within categories.
    The fact that it is community driven has the benefit that most major sport schedules, holidays and other events have a web calendar. Even several schools and universities have published their activities calendar here.
    A downside of this website is that quite a few calendars are outdated, no longer work or are listed multiple times by multiple people.
