Jay's age at... JSA retirement (Y18)=37; Year One(Y26)=45; Crisis(Y40)=59; Flashpoint(Y55)=74; Now(Y60)=79
Clark's age at... JSA retirement=17; Year One=25; Crisis=39; Flashpoint=54; Now=59
Bruce's age at... JSA retirement=11; Year One=19; Crisis=33; Flashpoint=48; Now=53
Barry's age at... Year One≥23; Crisis=37; Flashpoint=38*(because dead for 14 years); Now=43
Hal's age at... Year One≥25; Crisis=39; Flashpoint=49*(because dead for 5 years); Now=54
Babs' age at... Year One=12?; Crisis=26; Flashpoint=41; Now=46
Dick's age at... Year One=8?; Crisis=22; Flashpoint=37; Now=42
Tim's age at... Crisis=9?; Flashpoint=24; Now=29
Damian's age at... Flashpoint=10; Now=15
FWIW, with the slightly more compressed and IMHO more logical version of the timeline I laid out earlier (Year One still in Y26, but Crisis in Y36, FP in Y50, Now=Y54), most of those ages would be reduced by about six years (maybe four for Dick, one for Tim), which IMHO fits their history as we know it at least slightly better. YMMV, of course.
