Use of 'when' to indicate time
When answers the question "at what time?" It can convey the time of an actual event in the future or the past, or a nonspecific time that might occur. It can be used at the beginning of a sentence, or in the middle.
Ex: I'll do the dishes when I get home, since I know that there's quite a mess from last night's dinner that still needs cleaning.
Ex: It was snowing when I got to school yesterday, and we all sat around talking about whether we would be sent home early or not.
Ex: Matt knew that the fence needed to be fixed, so he said he would do it when he got a chance, and I believe him.
Importance of 'before' and 'after'
Before and after convey the order of events in time, whether earlier or later. They are crucial for establishing a sequence of events, and are very important in directions of any kind. Both can be used at the beginning or in the middle of a sentence and the same comma rule of when applies here as well.
Ex: Before cleaning out the vacuum cleaner, it is very important to make sure that it is unplugged.
There is no reason to risk an electrical shock.

Ex: Jennifer went home and did her maths homework, English homework, and science homework. After
that, she had dinner with her family.

'When' is used to answer the question "at what time?" and can refer to a specific or nonspecific time in the past or future. It can be placed at the beginning or middle of a sentence, as shown in examples like "I'll do the dishes when I get home."
While 'before' and 'after' share the comma rule with 'when,' they are not interchangeable as they specifically indicate the sequence of events, unlike 'when,' which focuses on the timing of an event.
