What does this tool do?
The remaining-day count is handy for annual budgets, deadlines and year-end planning. Leap years add 29 February, so a year contains either 365 or 366 days.
The Formula
Days left = days in year − day of year (+1 if the chosen day is counted)Frequently Asked Questions
Is today included in the remaining count?
The default includes it, which matches the way most people count days left in a year. Choose the exclude option to count only the days after the selected date.
How are leap years handled?
The year length switches to 366 days when the year is divisible by 4, except for centuries that are not divisible by 400.
