Yahoo has improved its online calendar which the search engine claims is easier to use and features added functions.
This compatibility, which will allow Yahoo users to share calendar data with users of those other services, is possible because Yahoo Calendar is built on open standards like iCalendar (iCal) and CalDAV, Kremer said.
Yahoo hopes that open calendar standards are adopted broadly not only among online service providers but also among makers of business desktop and mobile calendar software, so that Yahoo Calendar will become interoperable with those products, Kremer said.
The new Yahoo Calendar allows items to be dragged-and-dropped into the calendar, as well as to be color-coded, and users will be able to call up calendar views as detailed as a single event and as broad as a month. The new Yahoo Calendar also has a 'to do' feature for listing pending tasks and the capability to set up reminder alerts that can be delivered via email, instant messaging or SMS.
Future versions of the new Yahoo Calendar will also sync up bi-directionally with Microsoft Outlook's calendar and let users access Yahoo Calendar when they're not connected to the internet via integration with Zimbra Desktop. The new Yahoo Calendar is based on technology from Zimbra, which Yahoo acquired last year.
In the future, Yahoo also plans to add further integration with other of its services, such as Yahoo Maps, so that users can call up a map from within the calendar, Kremer said.
Users will also be able to subscribe to receive events from public calendars and event services like Yahoo's own Upcoming.org.
The new Yahoo Calendar will also give third-party developers the chance to build applications and extensions for it via APIs and its standards-based architecture, Kremer said.
