The day counter measures the exact number of days from a start date to an end date, automatically handling the awkward parts β months of different lengths and leap years (where February has 29 days). Simply enter both dates and it returns the total.
One thing to decide is whether to count inclusively or exclusively. The gap between two dates excludes the start day; if you are counting a span such as the number of days an event runs, add one to include both the first and last day.
Day counting comes up constantly: tracking notice periods and contract deadlines, working out a baby's or pet's age in days, counting down to a wedding, holiday or exam, or measuring how long ago something happened. Project managers use it to gauge durations, and finance uses it to count interest-accrual days.
For working days only, count the calendar days and subtract weekends and any public holidays in the range. Keeping a consistent definition of your start and end points avoids the classic "off by one" error that trips people up when planning around a deadline.
Enter a start and end date and the counter returns the exact number of days between them, automatically accounting for different month lengths and leap years.
By default it counts the gap between the dates. You can include the end day when counting a span (such as event days) by adding one to the result.
The basic counter measures calendar days. To estimate working days, subtract weekends and any public holidays that fall within the range.
Common uses include tracking deadlines, age in days, notice periods, project durations, and counting down to events like weddings, holidays or due dates.
