We used to fly "changaa" three months before Dasain.  Then for some reason, you would see virtually not a single changaa after Dasain... not even one.  That would be the start of "gucchaa" season which would go on all winter.

Do kids still fly "changaa" and play "gucchaa" nowadays?  Perhaps not as much.  Video game le keta-keti-haru-lai bigaaryo.
