How old is my character?

actually, not really, you must have 1-2 years max between now and ARR start, if your character did begin with ARR he is 18+2, same for the legacy since we was send throught time. at best 18+3.

My OP states my character started in 1.0. And you forgot the 5 years between the end of 1.0 > ARR. There are lot more years in between then and current day Eorzea I think.

Go to sleep silly elf!!!

As far as the Calamity years, I tend to omit them from my character's age because we were technically "frozen in time" for 5 years. I guess it would be up to your character herself to deem if those years are accountable to her age. Up to you if you want imo.

ahh yeah, well it's a matter of viewpoint there, up to each to see how they want to add it or not. without it you are between 20-22 and with it's about 25-27. the trouble is to know how many years did pass while we was playing, the safest guess is to count 1 years for each irl years.
when i think like this is more 5 years spend since the game did come out in 2010, even if we must take out almost 1 years with the different down of the game.

but without a confirmation of SE it's quite hard to know for sure.
