How long is a Sim year?

I play on Long and none of it ever adds up. One is called upon to suspend RL logic. It takes three days for a human Sim to fully gestate, which in RL might suggest one day equals a month in the Sim universe. But then we've got seasons. In RL a year is attached to four seasons. However, in the game, a Sim will age to the next level in far less than four season's worth of experience. It is the conundrum of the ages. I just wing it myself. Erik was 17 when he graduated early and went to Uni for three terms. At this rate, I surmise, he was all of 20 upon graduation. He now is married with the one child, an Infant, which suggests he's now 22 or will be soon. I tried to calculate it once, but I got lost along the way.

I play on long so it's 28 days for me, 4 weeks each season. I would have it longer but I don't want to install the mod that gives me that choice, yet.

I play with LittleMsSam's 21 day seasons so for me, my sim year 84(?) days.

Each season is set at 28 days, which is equal to a month in my mind, and I play each season 3 times before moving on to the next one. 4 seasons times three playthroughs equals one Sim year. I also play with aging off and age up my Sims when I feel it's the right time. I play rotationally through many families and single Sims, and when there are as many things to do as there are now in the game, I like to take my time with every Sim so they can experience everything without me feeling pressured to move through the game too quickly. That, plus I get very attached to my Sims and their stories and want them around for as long as possible.

I play on long seasons (28 days) and can't imagine going back to shorter ones. I enjoy being able to see actual transitions from one season to the next and having time to enjoy the weather before it totally flips again.

I play through all four seasons for a year. My seasons last 4 weeks (28 days). If I made the year any shorter, my sims would never go to work due to all the holidays I have added to the calendar.

Forever and ever or till last week.

4 seasons, each of them 4 weeks. I don't like to rush.

My Sims don't have years, I've never even thought of it.

It varies, depending on the save. As a general rule however, I play with aging off with a typical sim year counting 14 sim days per season x 4 unique seasons = 56 sim days.
Considering the fact that I have a bunch of different story saves, plus I don’t play a lot or for a very long time unless I’m ill or it’s weekend and the actual actual weather is too dreadful for me to be causing any trouble outdoors, it would literally take me an entire year or more to get through one sim year per save if that makes any sense?

It nearly took me a full sim day to write this. I could have been playing instead if I wasn’t “working” right now. ?
