Day Counter

This calculator works out exactly how many days sit between two dates, whether you are counting down to an event, working out how long has passed since something happened, or checking the length of a notice period, tenancy, or contract. Enter a start date and an end date, or use the quick countdown buttons for common New Zealand dates such as Christmas, New Year, Matariki, Labour Day, and Anzac Day, or enter your birthday to see how many days remain until your next one. The calculator instantly returns the total number of days as a headline figure, along with a breakdown showing the gap in years, months, weeks, and days, plus the same period converted into total weeks, hours, minutes, and seconds. A verdict line spells out the result in plain English, so you can see at a glance how the two dates compare. The count runs from the day after your start date through to your end date, the standard way of measuring elapsed time, and it automatically adjusts for leap years and the different lengths of each month. If you enter an end date before your start date, the calculator swaps them and lets you know. It is useful for tracking deadlines, planning events, working out how long you have been in a job or tenancy, or simply satisfying curiosity about how many days old you are.
