What is the difference between Present Simple and Future Simple for future events?

Present Simple treats future events as facts or fixed schedules ('The train leaves at 9:30 tomorrow'), whilst Future Simple expresses possibilities, predictions, and decisions ('I think the train will be late'). Present Simple is used for timetables, official programmes, and certain future facts, whilst Future Simple is used for predictions, spontaneous decisions, and uncertain future events.

When should I use Present Simple for future events?

Use Present Simple for fixed timetables and schedules ('The flight departs at 14:30'), official programmes and events ('The conference starts on Monday'), natural phenomena and cycles ('The sun rises at 6:15 a.m.'), conditional sentences with if/when clauses ('If it rains, we'll stay inside'), and certain future facts.

When should I use Future Simple?

Use Future Simple (will + base verb) for predictions and expectations ('The weather will improve next week'), spontaneous decisions ('I'll call you tomorrow'), promises and commitments, uncertain future events, and general future statements. Future Simple expresses what you think will happen rather than what is already scheduled.

Which tense do I use in conditional sentences?

In conditional and time clauses (after when, if, before, unless, etc.), use Present Simple for future meaning: 'If it rains, we'll stay inside' not 'If it will rain'. However, the main clause can use Future Simple: 'We will wait until the rain stops.' This is a common mistake - never use 'will' in the if/when clause itself.
