Thanked!
This is a pack of mods that modify Sim or pet lifespan in order to reflect one real life year as one Sim day – under certain assumptions.
Makes Sim pregnancy last 18 hours in total – 6 hours for each trimester.
In an unmodded game, it lasts 75 hours – 25 hours for each trimester.
Makes pet pregnancy last 4 hours.
In an unmodded game, it lasts 48 to 60 hours.
Assumptions:
Lifespan settings:
Additionally, elders can have additional -2 to 10 days (as in an unmodded game) 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.
There are 2 versions of this mod:
* If you have a mod that changes this time, my mod will use it instead of 6 PM.
Assumptions:
Lifespan settings:
There are 2 versions of this mod:
* If you have a mod that changes this time (such as Pets Age With Sims), my mod will use it instead of 11 AM.

If you have one of the following pre-release mods, delete it before you install these mods:
- simNopke-1yearAs1dayLifespan
- simNopke-1yearAs1dayLifespan-growUpNextDay
After you have installed any lifespan mods, only newly created Sims/pets will be affected by it. Already existing Sims/pets will use the new lifespan settings once they have grown up.
You may use Smart Age Correct by Chris Hatch and Lazy Duchess to update the lifespans of existing Sims/pets to match them to newly installed lifespan mods.
You may use Smart Age Correct by Chris Hatch and Lazy Duchess to update the lifespans of existing Sims/pets to match them to newly installed lifespan mods.
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.

In an unmodded game, it lasts 75 hours – 25 hours for each trimester.

4h pet pregnancy modMakes pet pregnancy last 4 hours.

| any mod that changes the same area as my mod, e.g. Sim lifespan or pet pregnancy duration | Don't use it with my mod. | For example, you can use the 4h pet pregnancy mod with someone else's Sim lifespan mod, but not with another mod that changes pet pregnancy duration. |
