How many days before April 20 2027 is December 21, 2026?
Exactly 120. The count starts the day after April 20, 2027 and ends on December 21, 2026, which is the convention almost every contract and deadline uses: the start date is day zero, not day one.

|---|---|---|---|

| January 2027 | 1 to 31 | 31 | 109 |
