So I have this grammar book and I noticed something strange. It says:

"Ahmet´in cezası daha ağırdı: Yirmi gün süreyle bahçeye çıkamayacaktı."

Then the translation says:

"Ahmet´s punishment was more severe: for three weeks he was not going to be allowed out into the garden".

"Yirmi gün" is 20 days, not 21? Is the translation wrong or is there some logical explanation for this?

Teşekkür ederim.

Only wrong translate

Thank you! I even started to wonder if they counted weeks differently in Turkey Silly grammar book, can´t trust anyone anymore

I think it can be always, dont worry about it. Kolay gelsin
