# Present Simple is used
## Arrangements
We use the [[Present Simple|present simple]] when we talk about future events that are part of some **OFFICIAL ARRANGEMENT** such as a timetable or programme
> Their plane arrives at 2 o'clock in the morning
> The next meeting of the committee is on November 5th
> We get off the train in Bristol and continue by bus

***Note***: we often use will + infitinitive in sentences like these with little difference in meaning
## Predictions
We use the present simple when we talk about personal plans or predictions IF we can make a definite, specific prediction because an activity or event is part of an official arrangement such as a timetable or programme
> There is a full moon tonight
> The sun rises at 5.16 tomorrow

## Clauses
In that- and wh-clauses when both the main clause and the that-/wh-clause refer to the future:
> I'll let you know when she **gets** here
# Present Simple is not used
## Predictions
We don't use the present simple when we talk about **PERSONAL PLANS** or **PREDICTIONS**. Instead, we use [[Present Continuous and 'going to' for the future|present continuous, going to, and will]]
> I'm really exhausted. I'm just staying in to watch TV tonight
> I think it will affect the rest of Europe soon
## Clauses
In that- and wh-clauses when the main clause refers to the present, we use **will** instead of the present simple.
