the day before
One day earlier
The day before refers to the day immediately preceding a specified event or time: The day before the wedding, everyone was scrambling.
Without further context, it often means yesterday or the day prior to whatever is being discussed: I saw him the day before, and he seemed fine.
The phrase emphasizes temporal sequence rather than simply naming a date.
