For being able to tell the time you need to learn numbers. When you are confident with numbers you can easily say what time it is.
Just like this:
9:15 – девять пятнадцать (nine fifteen)
12:30 – двенадцать тридцать
11:45 – одиннадцать сорок пять
15:00 – пятнадцать ноль ноль
20:20 – двадцать двадцать
You also may use the word “час” (o’clock). But there is one tricky thing you should remember when you use this word. It changes the ending. The ending depends on a number it’s following. If there is 2, 3 or 4, the ending is -а. For numbers 5 and more the ending is -ов.
But after the 20 the ending of the word ‘час‘ depends on the last number.
For example:
Сейчас 21 час – it is 9 pm.
Сейчас 11 часов – it is 11 o’clock now.
Сейчас 22 часа – it is 22 o’clock (10 pm).
