Junel, take the age as your lunar year.. the month is in English month...
For me, i conceived in Sep and according to Chinese Lunar calendar, I was 34 yrs old as I was born in year of Dragon even thou I born in Snake year (I was born 1 week before CNY in 1977).. So I look at Age 34, look at Sep, there u will able to see the gender..
Just for fun thou some of my frens said it accurate..
