In Finnish there is no future tense. You can use the present tense to express what will happen in the future.
For example:
Huomenna menen uimaan = Tomorrow I'll go to swim

Use "tenses": "How many tenses does Finnish have?" If you write "how many times...?", it sounds like a repeated action. (I really can't answer your question in Finnish, sorry.) :/
