I know zählen could also mean to count but only as in checking the quantity or going from one to a certain number. I'm not sure if it also means that something is included and is accounted for as done, as in "that time counts". How would you say such expression?
Also in a more specific context, like last week a tennis training session had to be canceled due to rain, and I wanna ask if that session is still counted as one more towards the end of the course, how would I say it?
