in (one's) day
When one was a child, teenager, or young adult. In my grandparents' day, you'd be a social pariah for marrying someone of a different ethnicity. I don't understand the way kids these days complain. Back in my day, the only thing we had to do for fun was stickball, and we were grateful for it!
in somebody’s day/time
1 when somebody was most successful, famous, etc: He had, in his day, been one of the greatest opera singers in the world.
2 at the time when somebody was alive; when somebody was young: In my grandmother’s time, women were expected to stay at home and look after the children. ♢ In my day, nobody would have spoken to the boss like that.
