Most and Least Likely Birthdates in England and Wales

The Office of National Statistics posted an Excel spreadsheet (xls) with day by day number of births from 1995 to 2016.
Posted on the occasion of the greatest number, 26 September, it shows it's not a fluke — it's in the middle of a period of more than average births.
No surprise when you think of it that the least number of births is on 29 February. On an average basis 26 December sees the fewest births and again is in a period of fewer births.
