"During that time wala naman pong January saka February. Ang simula po talaga ng mga months noon ay simula po talaga ng vernal equinox which is March hanggang December..Nahalata talaga nila na hindi pa rin nagre-reckon sa kanilang mga festivities...especially po doon pagdating sa determination ng Easter Sunday," Raymundo said.

"Nag-divide ngayon itong si Gregory. Nakita nila 'yong 11 minutes and 14 seconds nag-accumulate. So nagdagdag sila ngayon na bukod sa definition na every 4 years there must be a leap year, naglagay po sila ng panibagong ruling, so every 400 years, every centennial years ay magiging leap year ang isa pero yung tatlo hindi," Raymundo said.
