Indirect speech

Hi all,

Please fix my mistakes.

Adverbs and adverbial phrases of time change as follows:

1/Direct: Yesterday, a day ago, one day ago.
Indirect: The day before, the previous day, a day before, a previous day.

(That means the indirect forms of "yesterday" , " a day ago" , "one day ago" are either "the day before" or "the previous day" or "a day before" or " a previous day"
Ex:
Direct speech:He came yesterday = He came a day ago =He came one day ago.
Indirect speech: He said he had come the day before =He said he had come the previous day =He said he had come a previous day = He said he had come a day before)

2/ Direct: Tomorrow,a day later, one day later.
Indirect:The day after, the following day, the next day, a day after, a following day, a next day.

3/ Direct: the day before yesterday,2 days ago.
Indirect: 2 days before, 2 previous days.

4/Direct: The day after tomorrow, in 2 days, 2 days later.
Indirect: In 2 days' time, 2 days after, 2 following days, 2 next days.

Thanks
