Question: I have a question and this has bothered me for years. How did Doc know the exact date and time to wear a bulletproof vest by reading Marty's letter? We see what Marty wrote and it says "The night I go back in time" before he puts it in Doc's pocket but it never said the exact date or time of when the terrorists would attack Doc after Marty came back in 1985?

Back to the Future (1985)
Answer: Doc sees the video tape recording of the first part or the test so would know it was after that time, so he took precautions to protect himself from that point forward. Knowing it could be at any time from the test till later, he wore the vest to the test, and presumably would have continued wearing it after the test if that wasn't when it happened.

Answer: The answer is right in your question. The letter states "The night I go back in time." Doc helped Marty get back to 1985 at the exact date and time that he left. He set this date and time in the Delorean. We know that Doc has a penchant for remembering dates as one of the ways Marty proves he's from the future is that Doc told him the exact date and events of when he got the idea for the flux capacitor.
