Question

Какое время в английском? The day before yesterday he told me that he hadn't come home by 7 on Sunday

Answer 1

told-past simple

hadn't come- past perfect

Answer 2

The phrase "the day before yesterday" refers to two days before the current day. So, if today is Wednesday, "the day before yesterday" would refer to Monday.

In your sentence, it states that on Sunday, he hadn't come home by 7 PM. This implies that the person being referred to did not arrive home before 7 PM on Sunday.

To summarize, the sentence is discussing an event that occurred two days before the current day (the day before yesterday), where someone did not come home by 7 PM on Sunday.
