This is the time period of six months in Vedic Astrology in which Sun transits through Makar (10), Kumbh (11), Meen (12), Maish (1), Vrish (2) & Mithun (3) rashis respectively. It starts from 'Makar Sankranti' (around 14th January) every year. During this time interval 'Dinmaan' continuously increases every next day & 'Raatrimaan' continuously decreases. Direction of sun rise is seen to be changing from South-East to North-East. In these six months the seasons ('Ritus') of 'Shishir', 'Vasant' & 'Greeshma' come one after another for every two months.
