Google/Android tip: Birthday reminders
If you open up Google Calendar and choose the Add link under “Other calendars” (on the left), there’s an option to “Browse Interesting Calendars”. On the Interesting Calendars page is a “More” tab. On the More tab is “Contacts’ birthdays and events”. This magic calendar contains the birthdays and anniversaries for everyone in your Google address book, which of course is synced with your Android contact list. The next step is to get reminders somewhere where you’ll see them.
