People keep track of lots of things in their Google Calendars — meetings, business trips, due dates and conference calls. But when I started my summer internship at Google, I wondered why it wasn't easier to add calendar events for the fun stuff in life, like birthdays and sports schedules.

Now, when you look under "Other Calendars," click "Add," then "Browse Interesting Calendars" (or use this link to the Calendar directory), you'll find calendars for hundreds of teams in dozens of sports leagues — everything from the National Football League to the Korean FA Cup.

When you subscribe to your favorite team's calendar, you'll see every game listed, updated in real time with the score as the game progresses.

You can also subscribe to a "Contacts' Birthdays and Events" calendar, which will add all of your contacts' birthdays to Google Calendar. Data is pulled from your Gmail contacts and your friends' Google profiles.

Finally, we also have two new Calendar Labs features for you to check out: "Dim future repeating events" makes recurring meetings more transparent over time, helping more important meetings pop out, and "Add any gadget by URL" gives you the flexibility put any gadget you'd like in your calendar.
