How to use the Day Counter
See a date's day-of-year number, week position, and how many days remain in the current year.
Pick a date to inspect its position in the year. Use clean values and review the result label: year position snapshot.
Calendar calculations can be affected by timezone, inclusive counting, leap years, holidays, and local business-day rules.
