No, oakleaves are all over the map for me. In my Z8A, they leaf out at different times each year. My SQ and others have leafed out as early as late February and as late as late March. Even had SQ flower buds in March this year.

They drop off leaves at different times too. Ruby Slippers starts first in late November (or slightly later) while the others tend to wait a month longer (Dec - Jan) or they never loose them at all (in which case they drop leaves as they are leafing out or a tad later). Mild winters and protected locations are usually why they do that. RS, in its northern location, tends to reliably loose leaves in the Fall.

ok nice, so I will be bare for about 3-5 months. that's pretty good since they change color too, it will add to the mix and not just be green. im ok with that

In fact a few leaves, especially in milder climates, "never" fall off. They sometimes die but stay on the plant for a while.
