Thanks for the clarification. If nothing else, we know she is an adult chronologically as well as physically.
I can see why people pretty much ignore aging in the game. It's well-nigh impossible to keep up with the RP development for a character when you have to make sure to add 16+ years of mental and social development into a character you play for less than an RL month (total playtime) in an RL year. (Stuff that simply isn't happening IG.)
I think both players and DMs prefer ignoring the fast passage of time. If we didn't ignore it, some events will have lasted YEARS! (For example, it might be a tad embarrassing if rescuing the princess from the evil goblins takes almost 16 game years.) heehee
On a more familiar note, using this time calculation, Goldie was pregnant for approximately
4 YEARS! 
Yikes!
Far better to know the calculations and use when/if needed (thanks to those who supplied them), mostly sticking to estimates IG.
Thanks again, Team!
