How is the pitch count measured, and when do rest days start?

A pitcher's pitch count for the rest-day thresholds is determined from the first pitch thrown to the final batter faced. Rest periods start at the conclusion of the player's final pitching assignment on a given day, and the full-day rest requirement commences at midnight.

Under no circumstances can a player pitch on three consecutive days.
