http://news.bbc.co.uk/1/hi/magazine/8227268.stmIt's a date prospective parents try to avoid if told their baby is due on 31 August. In a society where parental ambition leads some to fake their address or religious faith to give their little ones the best start in life, 31 August is gaining a certain reputation.
Summer-borns tend to lose out at school because, in England and Wales, 1 September is the cut-off date for school entry, so they can be up to a year younger than their classmates.
Research by the Institute for Fiscal Studies two years ago found only 53% of girls and 47% of boys born in August reached the expected educational level at age seven in state primary schools in England, compared with 80% and 70% of those born in September. I'm sure Wenchy would argue that New Years Eve / day is just as bad a time to be born but for different reasons.
As would be February 29th or April 1st

Others would argue that any birthday is a bad day

So which is the worst ????
