Each year Hindus worldwide celebrate January 14th as Makar Sankranti – a day that marks the change of season as the sun enters the sign of Capricorn or Makar. Makar Sankranti ushers in longer days and the festivity symbolizes sunshine in life. To mark this occasion the Vedanta Society of Portland will offer a 'yogathon' on two Sundays January 14 & 28 from 8 a.m. to 10 a.m.
