Google Calendar

Google Calendar is a really useful tool for managing time. I've created separate calendars for personal events, work, study, birthdays and more. All of these show up in an easy to navigate web interface, and I can choose to setup SMS reminders for important events.

Perhaps the most useful feature for me is the automatic synchronization with my Android phone. I can add an event to my phone on the go, and when I get back to the computer it will already be there on my calendar. This saves a lot of time and frustration on my behalf.

Another feature that is often overlooked but can be extremely powerful is the sharing features. If someone gives me permission to see their calendar, I can view it alongside my own, and even schedule meetings where all people are free, just like Outlook but in the cloud.

Theres too many features to write about them all, but it's such a useful tool that I highly recommend it to anyone having trouble managing their time. Especially if need to be able to access the same calendar from multiple locations.
