Notes

The episodes "Silent Enemy" and "Cold Front" are placed in reverse airing order in this timeline. The reason for this is because "Silent Enemy" is explicitly said to occur on September 1, whereas "Cold Front" is said to happen 4 months, 3 weeks, and 6 days since Enterprise left Earth (April 13), which puts it on September 9.
