A/N: Sorry, no update to Returning Home, but please enjoy this weird, (il)logical, "non"fiction, mathy shit with no actual purpose. I have another one in the works about the Robins and their reasons for being unpopular. Red Robin is half done, and the others are in the planning stages.
Oh, and by the way, please no flames. I am well aware of the fact that I can't write.
Especially "nonfiction."
Bruce is Batman alone for a couple years (2 years?)
Dick is adopted at 8 and becomes Nightwing at 16 (8 years)
Jason becomes Robin at 13 one year after Dick is fired/quits (1 year)
Jason is Robin since 13 and dies at 16 (3 years)
Tim becomes Robin a few months after Jason dies (½ year)
Tim trains for a year (1 year)
Tim becomes Robin at 13 and Red Robin at 17 when Damian becomes Robin (4 years)
Damian became Robin at 10 and has recently celebrated his 13th birthday (3 years)

Bruce became Batman and started his war on crime at either 21 or 28 meaning that he is, at present, somewhere between 43 and 51. Even if you say he was only alone for one year, that only makes him 42-50. Even taking a year or two off Jason or Tim's time as Robin as well you get, at best, 39. At worst you get 49. Even claiming Damian started at 12 on top of all this, you make it 37-47. Bruce has lived a long time. DC has to eventually give him a rest.
So, the youngest possible age of Batman is 37, but he is most likely closer to mid to late forties. Possibly even early fifties.
Bruce- 37-51
Dick- 24-29 (although it may be slightly more as he started at 10 or 13 in some versions)
Jason- P(18-24) SB(22-27)
Tim- 16-20 (although, since he just got into college, I'd guess 18-20 is more accurate)
Damian- 13 (Teen Titans Rebirth #1 for confirmation)
Selina- 35-48 (she seems to be slightly younger than Bruce, but not by much, so I guestimated based on what I know)
Barbara- 25-42 (once, she was already 26 when she became Batgirl and Robin was 13 at the time. It was later retconned to make Barbara only 1-2 years older than Dick, not 13)
Cass- 16-22 (she is either Tim's age or a couple of years older. Making her minimum the same as Tim and her maximum 2 years older)
Steph- 16-21 (she seems slightly older than Tim, but it was confirmed that she was in the same grade as him)
A/N: Now, This is all guesswork, but I tried my best. I'd been trying to put it down on paper for ages. This was the result.
I know, it's horrible.
