Purna Prasad, rain is a word that is used as a verb, and a noun as well. As a noun, it means water droplets fall from could. Accordingly, there is nothing wrong if it's said that 'rain falls', 'rain stops', 'rain is falling', etc.
Again, when rain is a verb, it acts as an active verb in a sentence. We can use the simple present form of the verb such as 'it rains in Cherrapunji often' or 'it does not rain in Thar', etc. to convey a usual fact. Again we use the present continuous form of the verb to express what is happening right now i.e. it is raining.
Now, the point to be noted is that 'it is raining' and 'rain is falling' - both are correct. It is right that 'rain is falling' may not be a usual way to describe rainy weather but it does not mean wrong. The use is less but is not wrong.
Now, coming to the translation you asked for, you can say, the rain stops at 2 p.m. (or a.m.) every day.
Tried to express my views to the best of my knowledge.
