Sul Sul!

Today is something a bit different, with the expert help from the loveliest, beautifulest, stunningest, gorgeousest, talentedest, queens Lamare and Teaaddict, I have managed to change how my ageing system works!


So the long story short is;

  • The seasons are now 6 days long,

  • Depending on what time of day (and what day it is) determines their zodiac, automatically assigned at birth.

  • Pregnancy is shortened (27 hours),

  • Pet Pregnancy is now between 24-36 hours,

  • Special holidays appear as pop up if you have the calendar on the lot,

  • Ageing occurs at 12pm - instead of 6pm.

  • Edited version of the Summer Vacation / Winters Day mod by Phaenoh - to sync up with the holidays in this mod pack.

  • Edited calendar to fit what we needed. (Basically took the mesh from this MTS calendar set)

  • zz_TA_SimsCanAlwaysGetPregnantLOL.package - this is so that teens can get pregnant, and so can adults right up until they are due to age up, this is so that the game doesn't stop sims getting pregnant when it shows 1 day left etc as in theory they can still give birth in that time!

  • Sims can get pregnant no matter their age - teen and adult,

  • Slower skills,

  • 12 sim days = sim ages up by one day. 12 sims days = 5 real life years.

  • If you use the Sims-CODEX, it will show their birthday in their profile if you have the aging set up!


The long story is;

  • You can have any seasonal order, so i have it all set up to have a Summer / Fall / Winter / Spring. But if you are one of our Aussie sims you can swap this around, so Winters day will be in Summer, etc. Basically, Season 1 is "summer vacation"* and Season 3 will have "Winters Day".

    • The notification will always say "Summer Holiday" but obviously if you swap your seasons around you can easy tweak the text list (0x0000012D) to call it what you want!

  • Babies / Toddlers / Children / Teens will show only having "1 day left" and adults will have "8 days left" on age up. This may feel weird to get used to at first, but basically every 12 days they will only age up once. On their specific 'birthday'. So lets if you have a Gemini sim, they will only age up on Season 1 day 1 and Season 3 Day 1. Sims will live for 144 days to the end of their Adult stage, elders can have a further 8 days (aka 96 actual days) this is random as I have nuked the elder bonus', I did however, leave a -6 days chance if they age up badly.

  • Slower Skills - this basically slows down the time it takes to earn skills. I wanted more of a challenge and something to reflect the longer lifespan. This is not required and totally optional.

  • Seasonal Calendar edits;

    • Some days have special holidays, that you can decide if you want to celebrate these or not. You can also create and tweak your own via SimPE if you wanted. Just edit the text list with the instance number 0x0000012D, the days are then in order. If you add holidays into the blank ones it should automatically notify you in game.

    • Added extra images to display the extra days in the season.

    • You can add PTO to sims if you needed some extra days off for them to be at home when kids are off school.

    • You will only be notified of the special holidays if you have the calendar on the lot.

    • Added functionality to be able to set the day, season via the calendar too.

  • The reason why I set ageing to be 12pm, it is for a few reasons;

    • The first being able to see it's a sims birthday, then to be able to plan a party earlier.

    • The second being that sims born before 12pm will have one zodiac, sims born after will have the next zodiac.

    • The Season count down happens anywhere between 2am-8am, so it just seemed like a nice time to clear the season changing so then birthdays are not doubled up. If that makes sense... I hope it does.

  • So Teaaddict came through with this for me, its the Sims can Always Get Pregnant mod. What this basically does it overrides when the game thinks a Sim can get pregnant for. As the lifespan is technically way shorter now, adults only have 1 day to be able to get pregnant, but that doesn't work for me. Also, it doesn't work for me if I wanted a teen to get pregnant too. So now the game will not worry about how many hours a sim is pregnant for. They can get pregnant right up until their birthday.

  • Season 1 and Season 3 share the same zodiacs, Season 2 and Season 4 also share the same. Thus, allowing all twelve to be allocated a certain day. I did toy with having 3 day seasons to have a full year, but I found that seasons were not long enough to get the weather effects, such as snow etc, 6 days was the happy medium I came too!

  • I set pregnancy to be 27 hours, I found that this was the happy medium to not having babies too close / too long - tweak-able in SimPE, same for pets.

  • So the season / zodiac / holiday days are as follows;

    • Season 1 Day 1 - Gemini - Start of Summer Holiday

    • Season 1 Day 2 - Cancer

    • Season 1 Day 3 - Leo - Llama Fools day

    • Season 1 Day 4 - Virgo

    • Season 1 Day 5 - Libra

    • Season 1 Day 6 - Scorpio - Last day of Summer Holiday


    • Season 2 Day 1 - Sagittarius

    • Season 2 Day 2 - Capricorn

    • Season 2 Day 3 - Aquarius

    • Season 2 Day 4 - Pisces - Bonfire Night

    • Season 2 Day 5 - Aries - Spooky Day

    • Season 2 Day 6 - Taurus


    • Season 3 Day 1 - Gemini - Start of Winter Season

    • Season 3 Day 2 - Cancer

    • Season 3 Day 3 - Leo - Winters Eve!

    • Season 3 Day 4 - Virgo - Winters Day!

    • Season 3 Day 5 - Libra

    • Season 3 Day 6 - Scorpio - New Years Eve!


    • Season 4 Day 1 - Sagittarius

    • Season 4 Day 2 - Capricorn - Spring Clean

    • Season 4 Day 3 - Aquarius

    • Season 4 Day 4 - Pisces

    • Season 4 Day 5 - Aries - Lovers Day!

    • Season 4 Day 6 - Taurus

  • Now for how this ageing translates to real life ageing, of course I would love sims to have accurate ageing but honestly, it made the lifespan last WAY too long! So now each age up is almost 5 year increments. This mod is deigned in a way that when your sim is able to grow up, aka "1 day left" in their age bar - that is when you actually age them up, I know some people who will wait until the next day but in this case that gives them an extra 12 days. It is broken down as such;

    • Baby - 0.2 days long - 0 years Old On Birth - after 2 sim days there will be a notification to say that the baby is ready to age up. (2 sim days equals roughly a year in real life)

    • Toddler - 2 days left - 1-5 Years Old On Age Up

    • Toddler - 1 day left - Age up to child

    • Child - 2 days left - 5 Years Old On Age Up

    • Child - 1 day left - Age up to teen

    • Teen - 2 days left - 10 Years Old On Age Up

    • Teen - 1 day left - Age up to adult / move to college

    • Adult - 9 Days left - 20 Years Old On Age Up

      • Little side note here, when sims go to uni and move back, I just use the simblender to remove a day, making them "25".

    • Adult - 8 Days left - 25 Years Old On Birthday

    • Adult - 7 Days left - 30 Years Old On Birthday

    • Adult - 6 Days left - 35 Years Old On Birthday

    • Adult - 5 Days left - 40 Years Old On Birthday

    • Adult - 4 Days left - 45 Years Old On Birthday

    • Adult - 3 Days left - 50 Years Old On Birthday

    • Adult - 2 Days left - 55 Years Old On Birthday

    • Adult - 1 Days left - Age up to elder

    • Elder - x Days Left - 60 Years Old On Age Up - again, Elders have no bonus days they just have a random amount of days between 1-8 days. If they grow up badly they have a chance to have up to 6 days taken off them.

  • Plantsims have shorter spans - toddlers 5 days, adults 6 days, elders up to 6 days.

  • Pets have somewhere between 9-13 days lifespan. but remember this is timed by 12 so they around for a few years... we deserve longer lived pets!


Think that's everything! Enjoy!


CONFLICTS - Any aging mods, season changes, baby personality mod by Epi - though, Lamare has edited that to work!
