A few weeks or so of hypomania often turns into euphoric mania, which will continue for maybe about 2-3 weeks before turning into dysphoric/mixed mania. Mixed manias usually last 1-2 months. At worst, a few months straight, but that's rare now with my combo of meds.

Depression can last anywhere from a few weeks to maybe 2-3 months, sometimes with some mixing in between. Anxiety seems to be present no matter what, but most extreme during mixed mania.
