Births in UK

My daughter is 28th Dec. We’ve never met another. However, my mum, my sil and my niece all share the same birthday. My maternal grandmother and I are exactly 7 days apart, and my dad and his dad are exactly 14 days apart. In my little family, the three of us are clustered within 8 weeks.

An Aunt was convinced that a cluster of birth dates amongst siblings should be expected as it should in coincide with the mother's cycle, which makes sense and there is that pattern within most sibling groups within my family. 

On my Husband's side we have a  Christmas eve and Christmas day birthday neither of which is particularly pleased with.
My birthday seems quite common

In my family group of 12, 5 of us have a March birthday and it seems to be the month where I always know someone also with a March birthday.

My dad, his best friend and BiL all had the same birthday in September. Although BiL was a few years older.
