RebCalendar is a small yet powerful utility. It is the Calendar you always wanted Windows to have, instead of the small calendar linked to the clock, which sometimes you do not even have enough permissions to view.You can configure the holidays in the template files, called Calendar_.ini, located in the application folder, but it comes preconfigured with the holidays of Madrid and US as two different templates.You can add events double clicking on a date, although no alarms will be set. The size of the calendar can dynamically be set through the + and - keys and the transparency of the calendar can also be changed throught the context menu.
