MC 1.12.2. B3M 1.12.2-02, SereneSeasons 1.2.15. Without B3M, the seasons change, but with it, they don't.
What are the correct settings to expose for the duration of the day 5 times and change of seasons. Help(
My config - B3M (https://pastebin.com/wAeh06hc), SereneSeasons (https://pastebin.com/XBWAYY7K).

I have absolutely no idea what B3M is, but you're gonna need to be more specific other than "it doesn't work."

Our season cycle is completely separate from the day/night cycle, so there shouldn't be anything affecting it.

B3M (https://minecraft.curseforge.com/projects/time-speed-mod?gameCategorySlug=mc-mods&projectID=221053). With this mods for long nights and days I do not change seasons (29 days have passed). Is constantly Early winter(
Specify in the description of the mod that it is not compatible with B3M, as many use it.

It literally says in the description on their CurseForge page that they have support for us, so clearly it must work in some form. It sounds like they actively change our season time though, so you probably shouldn't change the day length in our config.

That mod takes full control of serene seasons, because it uses it's own month/date system.

When using this mod with serene seasons, new worlds start on january 1st, and thus during winter, and the seasons don't follow the 7-day-per-subseason, instead being based on the calendar. I'm trying to find a way to change both the starting date, and how long each month lasts.

If I can't, then people ought to turn off the serene seasons control in the B3M config, and use the same day time multiplier for B3M and serene seasons config
