Yahoo's New Calendar Application Now In Beta

The new Yahoo Calendar incorporates technology from Yahoo's acquisition last year of Zimbra, a company that specializes in open source messaging and collaboration software.

Yahoo Calendar users can color-code activities, drag and drop appointments, and incorporate Flickr images in their calendars from inside their Yahoo Mail accounts. Yahoo Calendar also includes a to-do list feature and e-mail, IM and text message alerts.

Additionally, Yahoo Calendar is compatible with calendar services from AOL, Apple, Google, Microsoft and Mozilla.

"With the new Yahoo! Calendar, we've taken the concept of a traditional paper calendar and transformed it into a smart, yet simple online tool that helps people to keep track of their schedules, stay organized and be more productive," said John Kremer, vice president of Yahoo Mail, in a statement.

"We're executing against our vision of a smarter inbox, and this is just a preview of what's to come in terms of integrating other network properties into the Yahoo! Mail experience. In the coming months, users will see additional features in Yahoo! Calendar to help them discover and keep track of their favorite events -- like sports team schedules and concert dates -- and even more features to enhance their overall communications experience."
