Questions & Answers about Αν βρέχει πολύ, ακυρώνω τη βόλτα στο πάρκο.

Why is the Greek sentence in the present tense when in English I’d usually say “If it rains a lot, I will cancel the walk”?

Greek very often uses the present tense to talk about future events when they are seen as:

• a general rule, or
• something that happens whenever a condition is met.

So:

• Αν βρέχει πολύ, ακυρώνω τη βόλτα στο πάρκο.
  literally: If it rains a lot, I cancel the walk in the park.

In context this often means:
“If it rains a lot, I (always) cancel the walk in the park.”
So it sounds like a habit / rule: Every time it rains a lot, my rule is that I cancel.

If you want to stress one particular future occasion, you can use the future:

• Αν βρέξει πολύ, θα ακυρώσω τη βόλτα στο πάρκο.
  If it rains a lot, I will cancel the walk in the park.

Notice also the change to βρέξει (subjunctive) with θα ακυρώσω — that’s a more “one-time future event” kind of structure.

What’s the difference between αν and όταν here? Could I say Όταν βρέχει πολύ, ακυρώνω τη βόλτα στο πάρκο?
