This is a bunch of mods that modify Sim or pet lifespan in order to reflect one real life year as one Sim day – under certain assumptions.

Update (22 Mar 2023): Fixed grow up next day versions of the lifespan mods because they didn't always prevent newborn Sims or pets from growing up on the same day they were born. Please redownload.
If you have one of pre-release packages (simNopke-1yearAs1dayLifespan or simNopke-1yearAs1dayLifespan-growUpNextDay), delete it before you install these mods.
Note that after you have installed any lifespan mods, only newly created Sims/pets will be immediately affected by it. Already existing Sims/pets will use new lifespan settings after they grow up. However, you may use Smart Age Correct by Chris Hatch and Lazy Duchess which updates life stage durations of existing Sims/pets in order to match them to newly installed lifespan mods.

18h Sim Pregnancy Mod
Makes Sim pregnancy last 18 hours in total – 6 hours for each trimester. Originally, it lasts 75 hours – 25 hours for each trimester.
Note that if a Sim got pregnant before you have installed this mod, such a pregnancy would not be affected.

4h Pet Pregnancy Mod
Makes pet pregnancy last 4 hours. Originally, it lasts 48 to 60 hours.
Note that if a pet got pregnant before you have installed this mod, such a pregnancy would not be affected.

Lifespan Mod – Sims
Assumptions:
  • Babies become toddlers when they're 1 year old,
  • Toddlers become children when they're 5 years old,
  • Children become teens when they're 13 years old,
  • Teens go to college when they're 20 years old,
  • College education lasts 4 years so young adults graduate when they're 24 years old,
  • Adults become elders when they're 55 years old
  • People live no more than 85 years.

Lifespan settings:
  • Baby: 1 day (3 days originally),
  • Toddler: 4 days (as originally),
  • Child: 8 days (as originally),
  • Teen: 7 days (15 days originally),
  • Adult: 31 days (29 days originally),
  • Elder (not plantsim): 10 to 20 days (11 to 21 days originally),
  • Elder (plantsim): 15 to 25 days (16 to 26 days originally).
Additionally, elders can have additional -2 to 10 days (as originally) depending on the aspiration level they had while growing up.

This mod does not modify college time. If you want to make it shorter, you may use Faster University Education by Dave Luv and Semester Changes by Cyjon.
You may be also interested in the 0 to 4 version of my College Dependent Adult Stage Days mod. It makes Sims who haven't graduated have their adult life stage longer.

Note that babies born before 6 PM will grow up on the same day after 6 PM. If you want to avoid it, use the grow up next day version instead. It makes such babies grow up next day after 6 PM. Use only one version at a time.

Lifespan Mod – Pets
Assumptions:
  • Puppies and kittens become adult dogs and cats when they're 1 year old,
  • Adult large dogs become elders when they're 8 to 9 years old,
  • Large dogs live 11 to 15 years,
  • Adult small dogs become elders when they're 10 to 11 years old,
  • Small dogs live 13 to 17 years,
  • Adult cats become elders when they're 10 to 11 years old,
  • Cats live 14 to 18 years.

Lifespan settings:
  • Puppy or kitten: 1 day (4 days originally),
  • Adult large dog: 7 to 8 days (22 days originally),
  • Elder large dog: 3 to 6 days (6 to 11 days originally)
  • Adult small dog: 9 to 10 days (26 days originally),
  • Elder small dog: 3 to 6 days (6 to 11 days originally),
  • Adult cat: 9 to 10 days (26 days originally),
  • Elder cat: 4 to 7 days (6 to 11 days originally).
Note that puppies or kitten born before 11 AM* will grow up on the same day after 11 AM*. If you want to avoid it, use the grow up next day version instead. It makes such baby pets grow up next day after 11 AM*. Use only one version at a time.

* 6 PM instead if you use my Pets Age With Sims mod

Conflicts
Do not use many mods that affect the same area, e.g. Sim lifespan, at the same time. In such a case, only one of them can work.

With caution, you may mix and match these mods with other mods that change pregnancy duration or lifespans.
