I usually say "last February" when I am talking about the most recent February that passed. Sometimes, I will say "this past February" to mean the same thing. If I say "this February" I usually am talking about the next one to come. To be extra clear, I say "this coming February." I also just remembered that if I say "In February..." Whether or not I mean last Feb or next Feb will be understood by my next words by what tense I use. Example: In Feb, I went to the zoo. vs. In Feb, I will go to the zoo.

Hi Hisako, Your friends are correct. As the month has already past, you'd say last February...this February would be meaning the coming February. Hope this helps you :))

I just want to add that if I'm talking now about February 2016 I would just say February. If I said "next February" I would be thinking about February 2017. At this time of year I think that saying "last February" is unclear. If for example my friend said she met someone last February I would immediately ask her if she meant 2015 or 2016. But if she said "last February" in March, I would think she meant the previous year, not the previous month. 上の答えは間違いないと思いますが、私は2016年2月を考えたら、ただ「February」と言います。2017年2月を考えたら、「Next February」と言います。 夏なので「Last February」と言ったらちょっとあいまいだと思います。３月で「Last February」と言ったら、絶対に今年ではなく、去年だと思います。 I hope this answer helps your study.

You can also say "This last February" because This February means the coming February.

I just say "In February" Last February to me, and to everybody I know, is February LAST YEAR
