rain or shine
No matter what the circumstances, as in We promised we would finish the project tomorrow, rain or shine. This term, first recorded in 1905, still refers to weather, as well as other uncertainty, and always implies that an activity will be carried out, no matter what. For a synonym, see hell or high water.
