Wow most are much shorter than what my settings are except Deshong, yours are longer, I have mine set at about 1/3 of Deshongs. 30 days per season so a 120 day year, and I just set each age span from that, for a 80 year life span so 9,600 days.

I set diffrent lifespans for diffrent games I play depending on how I feel about each one. Also I can't stand the proportion of the toddler and child stages to the others so I have a mod that changes the default lifespans so that the child stage is the same length as teen and toddler is about 1/3 the lengh of that.
So my default normal lifespan is...
Infant 3 days
Toddler 4 days
Child and teen both 14 days
YA and adult both 28 days to compensate for more time in the child stage.
This is the lifespan I I typically use with games that I play as sort of secondary to what ever game I am focusing on. For my "main" game(s) I use a custom set lifespan of 165 days
4 days for infant
7 for toddler
21 for child and teen
42 for YA and Adult.
28 min for elder
I find that this pace works just right for me. Enough time for each sim to get the most out of their lifestage with out being so long that there are long stretches of time without any changes and i start to get bored.

I often use a custom lifespan which is:
1 day baby
4 day toddler
7 day kid
7 day teen
21 days YA
21 days Adult
1 day Elder

I play with the default one. It is fine by me.

I'm back to my 85 day lifespan. I can't do long ones, I get too bored.

I play the game so that 1 year equals I sim day.
0-1 - baby (1 day)
1-5 - toddler (4 days)
5-12 - child (7 days)
12-19 - teen (7 days)
19-33 - young adult (14 days)
33-65 - adult (32 days)
65-80 (or more) - elder (15 or more days)
Whenever I enter MasterController and have a list of sims I can see the number of days they have, which equals the real age. For example:

I do that too! Although my age cutoffs are different

It's the most convenient span for me but there's one thing bothering me. Young adults turn into adults at the age of 33 in my game and IRL I'm getting closer to 33 more than ever before. It means I'll no longer be a young adult. It's really disturbing...

Lol, I am 33 so that is weird for me too! FWIW I base mine off of developmental psych so it's 40.
