This forum has become filled with people asking questions without doing the basic research and wasting the time of everyone else. So yes, for many of us, we don't just ignore posts. It is not a question of discouraging someone seeking knowledge, it is a question of discouraging expectation of spoon-feeding.
Now with your response it seems you asked the wrong question.
You should have asked how many days of holidays you need to compulsorily give.
The answer lies, first in knowing what type of organisation you are in (which you didn't even bother to disclose). But basically, you need to see your Standing Orders. If it is silent, then you need to follow general industry practice, which is 8 or 10 days a year including the 3 mandatory holidays.
