month of Sundays

Seemingly infinite duration

A month of Sundays is an indefinitely long time—since a month containing only Sundays would stretch across seven calendar months.

The phrase typically appears with negatives to emphasize that something won't happen or hasn't happened: I haven't seen her in a month of Sundays.

It suggests not just duration but a kind of pleasant impossibility, Sundays being days of rest.
