Imagine a website that offers paid plans to it's users. Paid plans are provided for periods of 1, 2, 3 months etc. But by saying month site developers mean 1 month = 30 days.
It's not stated nowhere at site that 1 month = 30 days, everywhere just # of months is shown. Is it legal to ask money for 1 month paid plan, not saying that 1 month = 30 days?
In case if it's not legal, should information about that 1 month = 30 days be situated at each page of the website? Or is it enough to put it only to one page in Help zone?
Can webiste say that 1 month = 30 days at all?
