This calculator will tell you the day of the week, and also the day of the year for any date: past, present, or future
Date to Calculate

Enter the date in MM/DD/YYYY form.

Note: We support past dates starting in the year 1000 A.D. However, different calendar systems were at place at different times, so the day may not match the historical record in all parts of the world, or before 1582 A.D.
