Minimum in-game day you can finish

[Vahan Nisanian]

The game begins on March 21, 1987. What's the minimum you can finish it on? I want to say May 29, 1987, but I'm not 100% sure.

Speedruns for the game seem to finish on April 11. Though keep in mind that’s for new game plus and playing from a new game would definitely take a lot longer.
