It may be the relaxed and happy times the Christmas-New Year holiday brings, with new figures showing September 28 - nine months later - is the most common birthday in New Zealand.
Statistics New Zealand has analysed birth data from 1980 to 2013 and has come up with the most common days for New Zealanders to be born on.
The 10 most common birthdays of 366 days all fall between September 22 and October 4 - nine months after the Christmas-New Year holiday period.
Statistics NZ senior demographer Kim Dunstan said the pattern for births in New Zealand was similar to the pattern for births in the United States.
"September and October are the most common months for birthdays with the 30 most common birthdays all appearing in the 38-day period from 12 September to 19 October," he said.
The least common birthdays tend to be clustered around public holidays, for example December 24-27, January 1 and January 2, Waitangi Day and Anzac Day.
Among those born on September 28 are actor Naomi Watts, burlesque performer Dita von Teese, singer Hilary Duff, actor Brigitte Bardot, singer Ben E King, boxer Francois Botha and New Zealand cricketer Doug Bracewell.
