"It is twenty to seven."
Translation:Yediye yirmi var.
With geçe/geçiyor (past) use the i type ending (i, ı, ü, u).. While with var/kala (to) you use the e type ending (e, a)... It's pretty simple thus you can guess the time with finishing the sentence (whether it will be past or to) just by looking at the ending of the hour. Yedi/yi beş geçiyor = it is five past seven... Yedi/ye beş var = it is five to seven
