No, it start with the midwinter (20-21 dec) and ends wit the spring equinox (20-21 march)
Ohh well,based on the Sun position.I have lost faith in Lelic when WFA was released.Even if i had WFA first,the implementation and the balance was very bad and still is.I am still thinking what should OKW do facing 2 vikers into bofors/mortar pit or both in 1vs1 and 2vs2.They take too much time to fix some easy balance stuff.
