I believe you will also need Story Progression and Master Controller to add those days off work as well.

Do you like player made towns? You could try Mesa Grande. It's a base game town with some CC that comes included. Of course, everybody's game experience is different but for me this town performs immaculately. There's no lag. I have the 1.5 version which has a unique sports center and more trees but I don't see it on the official forum post. Maybe I missed it...in any case the 1.5 version can be found here. The official forum post has a link to a Seasonal Festival lot as well as Ambitions lots if you decide to pick that EP up. That post is here.

The napping mats can be found here.

Forgot to put Ambitions and Showtime EPs up there...

I don't use much CC, but I use a lot of game enhancing mods:

When sims get married they used to be able to write "Thank you" notes to the guests, but a patch broke it.However someone created a mod to fix that.

This mod adds more prizes to the festival ticket booth

This one adds more recipes and plants

I love Ruby's home designs

This one adds longer seasons

This one let's you order "Delivery" from restaurants and also let's you buy "take out"
http://modthesims.info/d/413311/buy-takeout-and-order-food-at-restaurants.html

This one makes it so you you don't have "unlimited" food in your fridge, without it you could just buy the ingredients from the fridge.
This one makes it so you have to go to the grocery store and get ingredients.

@Mikezumi Thanks for the link. A nap mat seems more appropriate for some of my sims' families than carrying their little ones a ways to their cribs or them falling asleep anywhere!

@KatyFernlily Thanks! I'll check that out soon.

@GraceyManor Thanks! Those sound interesting! Especially Longer Seasons one (Will help me with my realistic sim families who I want to age after a year (all 4 sims seasons, currently 28 simdays...) which seemed a little short after I tried it... though maybe not, considering I made baby and toddler shorter since they're much more stressful on working sim families who can't afford a babysitter every single day (guess that's where logic comes in... one sim on day shift, one on evening, so someone's home at least, until they can afford a babysitter? )

Yeah, I love the seasons one, it maxes out at 84 days per season, so about 363 days total, almost a full year.

Is there a mod to add more holidays if you did do longer seasons?

@KatyFernlily thanks!
