Remember: if or when?
Use if for a condition or possibility. We do not know whether it will happen.
Use when to talk about the time something happens, for example a regular event, a past event or something expected to happen.
IF → a condition
If it rains tomorrow, we will stay at home.
Falls es morgen regnet, bleiben wir zu Hause.
Falls es morgen regnet, bleiben wir zu Hause.
WHEN → a time or event
When the film starts, we will sit down.
Wenn der Film beginnt, setzen wir uns hin.
Wenn der Film beginnt, setzen wir uns hin.
Tip: Ask yourself: Is this something that might happen (if), or am I talking about the time something happens (when)? In future sentences with if or when, we normally use the present simple after these words, not will.
