 A preposition shows the relation of a noun/pronoun with other words in a sentence.

Certain prepositions show the relation to that of time.

• At shows the time of the day, while on is used with days and dates.

 In is used with longer periods of time like month, year, seasons, etc.It is also used with parts of the day like morning, afternoon and evening.(But we say at night)

Words like for, during, while also show relation with time. for + a period of time during + noun while + subject + verb

 On time is used to mean at the time that was planned. The opposite is late.

 In time is used to mean soon enough or a little earlier than the appointed time. The opposite is too late.

 At the end is used to mean at the time when something ends. Its opposite is at the beginning. In the end is used to mean finally. Its opposite is at first.

Note: We don’t use prepositions with words like yesterday, the day before, last, this, next, and every.

We do not use a preposition when home and abroad proceed a main verb.
