I would like to know if there is a need for the word "year" in this part of the sentence:
"..., that took place from the 2019 to 2020,...".
Should it be:
"..., that took place from the year 2019 to the year 2020,..."
or
"..., that took place from 2019 to 2020,..."
I have searched for an answer, but I only found articles about dates. Thank you very much for your help.
