How can say to someone that I cannot take a vacation on a specific month? I came up with some phrases but I'm not sure if any of them are grammatically correct.
I don't have a vacation in July
I can't take a vacation in July
I don't have a holliday in July
Also, am I allowed to use vacation instead of holliday? I've been told that this is common in the UK but I'd like to confirm that.
