I'm in 4a and I would say they are late here but it would also depend on what daylilies you have (i.e. their typical bloom time in relation to each other, e.g. EE, E, M etc.). I have scapes with buds here on Hemerocallis minor, H. lilioaphodelus and 'Flavina' that I've noticed so far. Some years lilioasphodelus (syn. flava) would be in bloom by now.
