Your age by chinese lunar calendar can be a bit complicated one. Generally, just add 1 to your gregorian calendar age. But if you are like me, was born a few days before the chinese lunar new year, then need to add 2 years.
eg: I'm born in 1983 (year of the pig for most people) but I was born before CNY, so I was still in the year of the dog. So by the chinese calendar, I was born in 1982, year of the dog (then you add the extra 1 year later to convert to the age by chinese lunar calendar). So I'm 25 by the gregorian calendar this year but 27 by the lunar calendar.
