If this is in the wrong forum, could the mods move it please.
I’ve been reading with interest the charts that predict your childs sex. There’s one here http://www.parentsplace.com/pregnancy/getready/pages/0,239161_438396,00.html and there also one one braxtonhicks’ website. Anyway, ‘apparently’ legend has it that the chart was buried in an ancient tomb and only found recently. My question is this - Does the age of the mother, in the left column, need to be calculated in lunar years or western years.
