The evolution times changed a little on the V4.
Also, it's not so much about it's age in years but
how long in hours it is a baby / child, etc.
Previously (V1s - V3s) you had a teen for 3 days (72hrs) before it evolved into an adult.
On the V4 you have a teen for 2 days (48hrs) before it evolves into an adult. Then you wait another 1 day (24hrs) before you get an invite to go Job Hunting
Just for the record:
Baby = 1hr, then evolves into Child/Toddler
Child/Toddler = 24hrs, then evolves into Teen
Teen = 48hrs (V4) or 72hrs (V1-V3), then evolves into Adult
These evolutions are based on an UNPAUSED tama. If you pause them you wait longer for them to evolve
