Translation:The season is from February to March.
No, lesliegirl. The à with the accent turned that way (to the left) is only used whenever you would use two as in a row.
"Eu fui a a escola" = "Eu fui à escola"
When in doubt, a+a can always be replaced by para a (to the). If that is the case, you should be able to put the à there. Another way to check is to see if the next word was masculine, if it would be "ao". ao is used before masculine words, and à (a a) is used before feminine ones.
Another case is:
"Eu fui a aquela escola" = "Eu fui àquela escola" (I went to that school), again a case of a+a.
I hope it helps! =)
I see your logic, and it would work in English, but not as a translation of the current sentence… because if that were the case, we would not use "vai" (we don't use "vai" as a translation of runs--meaning "works"). Maybe we'd use "funciona" (works) instead. I hope it helps! =)
