While reading my manuscript, I realized to my embarrassment that I apparently have difficulty depicting the difference between weeks or months passing, so it's not always clear when everything is happening. So one of the first things I did before diving in to revisions was print out blank calendars! Fun!*
I then proceeded to fill in every major event, the exact day it occurs. It was dorky but made me feel settled, and ready to edit.
P.S. The photo is deliberately blurry as opposed to my usual "accidentally blurry." Can't give away all my plot secrets.
*I'm not being sarcastic. It was really fun!
