Think paper calendars are so 20th century? An online version allows you to maintain an ultra-organized system and share it with others. Try these tips:

Set the calendar to alert you to upcoming events — ideal if you tend to forget birthdays and anniversaries (ahem). Look for repeat features that let you input the data only once.

Choose a calendar that can send text-message and e-mail reminders to your cell phone and you won’t miss Sally’s dance recital.

Opt for a calendar with comprehensive holiday listings — from Groundhog Day to Grandparents Day — so you won’t have to type them in yourself.

Shown: With the UVC Basic calendar, you can choose a daily, weekly, or monthly configuration.
