About this tool
This page opens the day-of-week calculator with its single date field ready to fill in. Enter any date on the Gregorian calendar and its weekday name appears immediately, shown in your interface language.
Working out a weekday by hand means counting through leap years and month lengths, which is exactly the kind of arithmetic that produces off-by-one mistakes. The calculator applies the same rules every time and returns an answer that cannot drift with your local time zone.
Alongside the weekday, the tool shows the date’s ordinal position in its year and how many days remain until the next New Year — useful context whether you are checking a single date or comparing several.
Example. 29 February 2024 is a Thursday, day 60 of 366, with 306 days remaining. 1 March 2025 is day 60, because 2025 is not a leap year. 31 December reports 0 days remaining.
Limit. The date is a UTC calendar day with no time of day. Days remaining do not include the selected day. Week numbers are not computed on this page.
