Summarizing winter breaks for soccer

I want to provide some insights on winter breaks in German football. The German FA, DFL, schedules a winter pause each season, usually occurring after the last match before Christmas, around Matchday 16 or 17, and resuming in early January. The typical break lasts 2-3 weeks, though historically it could be 4-6 weeks. I’ll provide examples from recent seasons and note that exact dates may vary based on matchdays and official announcements by the DFL.
下面按常见关切做个简明梳理。
时间(通常在每季中哪里)
设立原因(为什么要有冬歇)
持续时长(一般多长)
近年示例(仅作参考,精确日期以当季DFL赛程为准)
如你关注某一具体赛季(例如本赛季德甲)的精确开始/结束日期,我可以按该赛季为你列出德甲与德乙的官方冬歇区间与轮次衔接点。
