Seasons: Advent Ideas?

As far as I know it isn't possible 😔 At least not in a vanilla game. That is why my sims often light menorah and/or holiday tree when they want to complete the festive lighting. I think the forest of lights menorah is very pretty, so my sims often use that.

Thanks. I may have to take a look at the various existing options, to see whether any of them might work well enough. Many Advent wreaths and candle holders use 5 candles (lighting a final "Christ candle" on Christmas day), which is like a Hanukkah menorah minus 4 candles, or a kinara minus 2 candles. Or maybe there's a Christmas holiday tree that will work well.

Wow, a new Sims 4 player, welcome!  Good for you to start with Seasons pack. 

• Now, you're starting with Summer, I recommend the following packs to go with the season: Island Living, Adventure Awaits, Backyard, Rivera Retreat Kit & Poolside Kit.                                                               
• For Autumn, I recommend the packs: Life, Spooky & Paranormal. 
• For Winter, Snowy Escape Pack. 
• For Spring, I recommend the packs: Enchanted By Nature, Cottage Living & Romantic Garden.                                                         

Wow... Do you get a commission from Electronic Arts? 😉

I've been playing for a while, although I've only recently started adding packs to my game. But I think I'll wait to add more packs until I've explored the ones I already have a bit more.

Hmm... There are various items in Build mode that look appropriate, with a group of 4 candles: Caress Scented Candles; Pine Fresh Candles; and Four Festive Candles, ho, ho, ho!

And there are pairs of candles where two of them could be arranged in a group of four: Candlelit Holly Branch, and Candlelit Fall Leaves.

But I suppose none of these will count towards the Festive Lighting tradition, right? 🙁 

No, I'm just a basic player that loves themes, especially seasonal themes.  I've been playing Sims 4 since September 2014.

Unfortunately it's only the tree, menorah and kinara that count towards the festive lighting tradition, the menorah can be lit one candle at a time so that may work towards your advent idea, and if you're into mods I saw a few that add advent candles/wreaths that I think do count towards the goal but I'm not 100% sure about that as I don't have mod access on PlayStation. I had the same problem in my game but I still get my sims to light candles as part of their holiday celebrations even though it doest count towards a goal. I added Christmas eve and boxing day to my calendar and on boxing day I get each of my household sims to light a candle on the beach near the shoreline in remembrance of the merfolk of the past and the island spirits of Sulani and it's still fun. If you don't mind that it won't be counted towards the tradition you could fashion your own advent out of build mode candles and have your sims do it anyway. I really wanted to use the candles that float in the water from the city living pack but I couldn't get them to place onto the sea, seems they only work on swimming pools 😮‍💨 I would love more items to be added to the festive lighting tradition! 

According to Google AI any candle that has the Light Candle interaction in live mode should fulfill the festive light tradition. If I remember correctly the Diwali lamp also had this option for festive lightning. Also, Life and Death EP comes with lots of candles and also the Eco living pack has lots of craftable  candles too. 

I found this interesting and promising, so I playtested it, but unfortunately it didn't work. I made the candles in the picture with the Eco Lifestyle candle making table. There was option to light and extinguish them, but it didn't have any animation and didn't count to festive lighting tradition. I think the diya in the picture is the Diwali lamp you meant. Sadly it didn't work either. It has the same kind of lighting option as the Eco Lifestyle candles 😔

Yeah, and I also discovered that not all candle-like objects available as holiday decor in build mode have the "Light Candle" interaction. But it looks like the Festive Lighting tradition really is limited to a Holiday Tree, a Menorah, or a Kinara. 😥
