How this is calculated
- Dates use Eastern Time (America/New_York). Remaining-year counts exclude the reference date and include December 31. Weeks remaining are full seven-day blocks, with remaining days shown separately.
- Gregorian leap years are divisible by 4, except century years unless divisible by 400.
How to use the day of the week
Enter any date from year 1 to 9999 to see its day of the week, along with its week number and day of the year.
Example
July 4, 1776 was a Thursday.
Common questions
- Which calendar is used?
