January 4, 2027 falls on a Monday
January 4, 2027 is a Monday. It is 102 days from today, September 24, 2026. The date is day 4 of 365 in 2027, it sits in ISO week 1, and it is the 4th of a 31-day month with 27 days after it.
What day of the week is January 4?
In 2027 it is a Monday. The weekday is not a property of the date itself, it is a property of the date in a given year, so the honest answer always names the year. A common year is 365 days, which is 52 weeks plus one spare day, so a fixed date moves forward one weekday from one year to the next. A leap year inserts a second spare day, so the step is two whenever 29 February falls inside the gap. That is why January 4 works its way around the week rather than repeating on a tidy schedule.
January 4 in the next few years
| Year | Weekday | Day of year | ISO week | Leap year |
|---|---|---|---|---|
| 2026 | Sunday | 4 | 1 | no |
| 2027 | Monday | 4 | 1 | no |
| 2028 | Tuesday | 4 | 1 | yes |
| 2029 | Thursday | 4 | 1 | no |
| 2030 | Friday | 4 | 1 | no |
| 2031 | Saturday | 4 | 1 | no |
| 2032 | Sunday | 4 | 1 | yes |
| 2033 | Tuesday | 4 | 1 | no |
Between 2026 and 2027 the weekday moves from Sunday to Monday, a step of 1. The day-of-year column never moves for this date, because January 4 comes before 29 February and so is untouched by the leap day.
How often does January 4 fall at a weekend?
Counting the 28 occurrences from 2027 to 2054, January 4 lands on a Saturday 4 times and on a Sunday 4 times, so 8 of those 28 years put it at a weekend. Over a full 28-year stretch the Gregorian calendar repeats itself, and a fixed date visits each weekday four times, so the long-run answer is two weekend years in every seven.
Where January 4 sits in the calendar
