Calendar Blocks JNL was inspired by old-fashioned wood type used to assemble calendar pages in the days of letterpress printing.

The A-Z keystrokes contain the dates 1-26. The lower case a-z keystrokes have the remaining dates 27-31, along with the split dates 23/30 and 24/31 and blank boxes.

The days of the week are located on the 1-7 keys.
