Can anyone tell me, if I arrive on November 5, and leave on December 4, I need to make a visa or can I still do without it? If you count the day of arrival 5 and the day of departure 4, then it turns out that I will be on the island for exactly 30 days. Thanks!

This is normal for stamp. That is, when entering on November 5, you will be stamped that you must leave Thailand before December 4 inclusive. Which is what you're going to do. No problem.
