Zettelkasten/Patterns/Monthly Template Pattern
From charlesreid1
The monthly template is a simple box that goes at the bottom of the page. It contains an organized list of links related to a given topic. You define a template like {{January2016}} and it is a Flag with a list of links to every daily page in January: [[20160101]], [[20160102]], etc.
For an example, see {{January2016}}.
The monthly template also links to the monthly template to the prior and next months, so that a daily page like [[20160101]] would include the monthly template {{January2016}}, which would link to every other daily page for that month, but also link to {{December2015}} and {{February2015}}.
