in somebody's day/time

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!
