yCal is a calendaring app to help keep the overview on a whole year. It features a unique "months by column" year view in addition to the more conventional week views, provides ample marking and note taking options, and central holiday and birthday management.
yCal has been designed from the ground up to make a better desktop calendar. Its unique year view gives you the perfect overview in a fraction of a second. Days can be marked in different colors and styles to give you more information in one picture (e.g., to show days of vacation, times of travel etc.) just like on a normal paper calendar. The full year can be shown side-by-side with the week view, giving you more fine granular access to individual events.
Everything is optimized for giving you access to powerful features with minimum user interface overhead. For example, just hit space in the year view to quickly look at the details of a selected day. Or just start typing to add a note. Swipe left or right to scroll through years and weeks.
yCal seamlessly integrates with calendars set up in OS X there is no proprietary data store. Use your existing data from local calendars, CalDAV servers, iCloud, or from wherever else without the need for importing or copying. All your changes will be sync'ed to all your servers and devices by Apple's iCal or Calendar app.
Note: Now requires OS X 10.10 or later
