Find the weekday, day of year, week number and days left in the year for any date.
Every date has a story: the weekday it fell on, its position in the year, how much of the year was left. This calculator answers all of it in one look — useful for birthdays, historical dates, planning, or settling an argument.
It also shows the week number, which matters for scheduling in many countries where plans are organized 'week 34' style rather than by month.
Exact — it uses your browser's native calendar, which follows the standard Gregorian rules including leap years.
Weeks start on Sunday in this calculation (US convention). If your region counts from Monday, the number may differ by one.
