The noun time can be used as both a countable and uncountable noun. (O substantivo time pode ser contável ou incontável.) Here are the example sentences.   Uncountable: I had a little free time when I was at the University. If you want to see everything, you’ll need a lot of time. I don’t have too much time these days. My students spend a lot of time studying Maths. Countable: I have been to Argentina many times. The last time I went there was in 2009. I have seen "The Lion King" a few times. We have met several times before. Is it clear? If it isn´t, please, write your doubt. Thanks.
