Keep birthdays organized electronically across multiple platforms with Google Calendar, or sign up for websites such as BirthdayPal.com or HappyBirthday.com for free birthday reminders. A good pen-and-paper system involves keeping a visible birthday list in a high-traffic area. Perpetual calendars, birthday books and day planners are also great tools.
Access Google Calendar online or via mobile on a smartphone. Enter birthdays into the calendar, and adjust settings to send notifications and reminders.
Enter birthdays into BirthdayPal.com and receive up to four different reminders per birthday. HappyBirthday.com assigns each user his own Web page. Users can direct friends and family to the page to input their birthdays themselves, rather than having to collect the information.
Perpetual calendars are a great resource for keeping track of birthdays because unlike a traditional calendar, they do not name the day of the week for each date. This way, the same calendar can be used year after year.
