What is triggered on the 2nd day of each month?

I'd like to know what stuff is triggered at the 2nd day of each month. And if possible I'd like to know, how can I log triggered event.

Because from time to time I happen to get a strange crash to the desktop, exactly on the 2nd day of the month.

Yes, my scientists also level up on the second of the month if researching.

Well, this part is responsible for triggering events every tech increase (i.e. 2nd day of month):

# A country has increased the level of a tech, use last_increased_tech trigger to check tech and level.
# This = Country
on_tech_increased = {
    events = {
        tutorial.6
        tutorial.64
        tutorial.73
        crisis.2190
    }
}

Tutorials for me are disabled and "crisis.2190" is responsible for possible beginning of AI rebellion.
