How to Add a Holiday or Sports Schedule to Any Calendar

Adding a holiday calendar or your team's game schedule keeps important dates on your radar without typing them in by hand. This guide shows how to add a holiday or sports schedule to any calendar by subscribing to a trustworthy .ics feed — and why subscribing is almost always better than importing.

This is the single most important decision:

	Subscribe (URL)	Import (file)
Events stay linked to source	Yes	No
Schedule changes flow in	Yes (auto)	Never
Easy to remove later	Yes (one toggle)	No — events are scattered into your calendar
Clutters your real calendar	No (separate calendar)	Yes (events become yours)

Importing dumps every event permanently into your own calendar. If a game gets rescheduled — common in sports — your imported copy is now wrong, and removing dozens of stale events is painful. Subscribing keeps the feed in its own read-only calendar that updates itself and toggles off in one tap. Always subscribe for holidays and sports.

Find a reputable feed

The feed is only as good as its source. Look for:

Official publishers — a league, team, government holiday office, or well-known calendar provider.
Clear "subscribe" or "add to calendar" links ending in .ics or starting with webcal://.
A recent update date, so you know it's maintained.

Avoid random third-party feeds that could inject spam or inaccurate events — a subscription can keep adding events to your view over time. When in doubt, prefer the official source. Many calendar apps also include built-in holiday calendars you can simply switch on, which is the safest option of all.

Built-in shortcut: Google Calendar, Apple Calendar, and Outlook all offer regional holiday calendars you can enable in settings without any URL. Try that first.

Once you have the feed URL:

Apple Calendar

Mac: File → New Calendar Subscription, paste the URL, Subscribe.
iPhone/iPad: Settings → Calendar → Accounts → Add Account → Other → Add Subscribed Calendar, paste the URL.

Full steps: subscribe on iPhone and Mac.

Google Calendar (web)

Open Google Calendar in a browser.
Click + next to Other calendars → From URL.
Paste the feed and click Add calendar.

Outlook (web / Microsoft 365)

Go to Calendar → Add calendar → Subscribe from web.
Paste the URL, name it, and confirm.

For the generic version of these steps, see subscribe to a calendar by URL. For what these links are, see what is an .ics file.

Tidy it up

Give the calendar its own color so games or holidays stand out — for Apple, see color-code calendars on Mac.
Name it clearly (e.g., "Lakers 2026" or "US Holidays").
Toggle it off anytime instead of deleting — handy in the off-season.

Expect a refresh delay

Subscribed feeds don't update the instant a game is rescheduled. Google and Outlook refresh on their own schedule (often hours); Apple lets you choose. This is normal — see why subscribed calendars don't update instantly.

When importing is okay

Importing makes sense only for a fixed, one-time list you never expect to change and want to edit yourself — for example, manually entered personal dates. For anything a publisher maintains (holidays, sports, public schedules), subscribe.

Troubleshooting

Feed won't add — try swapping webcal:// for https:// (or vice versa).
Events look old — that's the refresh interval; see the linked guide above.
Wrong times — usually a time-zone quirk in the feed; check your calendar's time-zone setting.

If you use Google and Outlook, nocal unifies those calendars into one timeline — see how.

Subscribe, don't import
