Yhe Writer Template for LibreOffice Themed Calendar, that inspired me to make at Calc calendar in same format, that can be used for all years.

This template is no longer available at LibreOffice Extensions and Templates.

The author made a similar template: 2014 LibreOffice themed calendar - with some USA holidays - letter size paper that is very much same design.
Though made with american standards. E.g letter size paper.
