eli5: Why did we design the months in such a way that winter is in January, February and December in a given calendar year?

Idk if this is a stupid question or not lol. Obviously when moving from one year to the next, January is right in front of December, e.g. December 2023 is right behind January 2024, but is there a reason that months were designed so that winter carries on into the next calendar year?

We have 12 months and 4 seasons, so each season perfectly divides into 3 months a season. With that in mind, why didn’t we design the months so that winter is in 3 consecutive months within the same calendar year?

I’m not sure if I’ve articulated what I mean properly, so let me know if further clarification is needed.

Seasons don’t switch precisely at a given date each year. Mother nature doesn’t care about our calendar.

If you moved things such that winter was reliably no longer split by the year boundary, then that’d just mean that autumn or spring would get split.
