According to one Facebook community page, January 17 (and the 17th of each month) is National Send a Handwritten Letter Day. At LetterMo, we think any time is the good opportunity to send a note, a greeting card, a novella–cheers to you, 12-page letter writers–or even an upcycled DIY postcard.
We have updated our annual list below. Click on the picture to view a larger copy or download the PDF below to print from home.
What are some other official or unofficial reasons to write? Let us know in the comments.
