If it always seems to be a "something day" in terms of observance across the land that's because there are indeed a lot of observance days and anniversary days on the
calendar.
Around about 40, give or take.
In strict observance terms it starts with New Year's Day and wraps with Boxing Day, and along the year's path there are events like Anzac Day, Good Friday, Easter Monday, Mother's Day, Father's Day, Waitangi Day, Queen's Birthday, Valentine's Day, White Ribbon Day...and so it goes.
Then there are the anniversary days like our fine region's day which very wisely (and obviously well planned) ties in nicely with Labour Day to create an extra long weekend.
In January alone there are four anniversary days — Auckland, Wellington, Northland and Nelson, and across the first half of the year leading into Queen's Birthday on June 4 there are 19 anniversary or observance days.
