5 do 12h

This phrase, "5 do 12h," is a colloquial Polish expression roughly translating to "five to twelve" or "five minutes to twelve." Its meaning is figurative, signifying that something is happening at the last possible moment, at the eleventh hour, or just before it's too late. The "twelve" refers to the hour, implying a deadline or critical point in time. The "five" indicates the very short period remaining before that deadline is reached.

The phrase is often used to describe a situation where an action is taken or a problem is addressed with very little time to spare. It implies a sense of urgency and potential for failure due to the lateness of the action. The connotation suggests that the situation was allowed to progress to a critical point before being dealt with. Therefore, it often carries a negative implication of procrastination or poor planning.
