The 2028 calendar has 366 days. It is a leap year, opening on Saturday, January 1, 2028 and closing on Sunday, December 31, 2028.
2028 has a curious shortfall.
Despite being a leap year with an extra day, it contains only ten observed federal holiday dates — the fewest of any year this decade — because New Year’s Day 2028 falls on a Saturday and its observance was taken by Friday, December 31, 2027.
The year gains a day from the calendar and loses one to the observance rule.

2028 federal holidays
Dates below follow 5 U.S.C. 6103 and the observance rules. Note the first and last rows: one holiday belongs to 2028 but is observed in 2027, and one shifts backward inside the year.
| Holiday | Statutory date | Observed | Weekday |
|---|---|---|---|
| New Year’s Day | January 1 (Saturday) | December 31, 2027 | Friday |
| Birthday of Martin Luther King, Jr. | Third Monday in January | January 17 | Monday |
| Washington’s Birthday | Third Monday in February | February 21 | Monday |
| Memorial Day | Last Monday in May | May 29 | Monday |
| Juneteenth National Independence Day | June 19 | June 19 | Monday |
| Independence Day | July 4 | July 4 | Tuesday |
| Labor Day | First Monday in September | September 4 | Monday |
| Columbus Day | Second Monday in October | October 9 | Monday |
| Veterans Day | November 11 (Saturday) | November 10 | Friday |
| Thanksgiving Day | Fourth Thursday in November | November 23 | Thursday |
| Christmas Day | December 25 | December 25 | Monday |
Only two of the eleven shift in 2028, and only one of those shifts within the year. Compare 2027, where three shifted and both year-end holidays moved.
Why 2028 has ten federal holidays, not eleven
A federal holiday falling on a Saturday is observed the preceding Friday under 5 U.S.C. 6103(b). New Year’s Day 2028 falls on Saturday, January 1, so its observance lands on Friday, December 31, 2027 — inside the previous calendar year.
Nothing comes back the other way. New Year’s Day 2029 falls on Monday, January 1, 2029 and is observed on that date, in 2029. So 2028 gives one away and receives none.
The statutory count is unchanged at eleven holidays per year. What moves is which calendar year the observance falls in. 2027 gained the extra and carried twelve; 2028 carries ten.
How the 2028 calendar compares to 2027
| 2027 | 2028 | |
|---|---|---|
| Total days | 365 | 366 |
| Leap year | No | Yes |
| Opens on | Friday | Saturday |
| Closes on | Friday | Sunday |
| Weekdays | 261 | 260 |
| Weekend days | 104 | 106 |
| Observed federal holidays in year | 12 | 10 |
| Holidays shifted by weekend rule | 3 | 2 |
| Working days | 249 | 250 |
2028 has an extra calendar day but one fewer weekday, because both the extra day and the year boundary land on weekends. It still finishes with one more working day than 2027, purely because it observes two fewer holidays.

2028 Calendar Quarters & Leap Day
- Q1 (91 days):Jan 1 – Mar 31 (includes 29 days in February)
- Q2 (91 days): Apr 1 – Jun 30
- Q3 (92 days): Jul 1 – Sep 30
- Q4 (92 days): Oct 1 – Dec 31
How many days, weeks and working days in 2028
2028 contains 366 days, 52 full weeks plus 2 days, 260 weekdays, and 250 working days.
The calculation:
- 366 total days, because 2028 is divisible by 4 and is not a century year.
- 366 ÷ 7 gives 52 complete weeks with 2 days remaining. Because the year opens on a Saturday and closes on a Sunday, those two extra days are a Saturday and a Sunday.
- 106 of the 366 days fall on a Saturday or Sunday, leaving 260 Monday-to-Friday weekdays.
- All ten observed federal holidays fall on a weekday, so 260 − 10 = 250 working days.
The 250 figure assumes a standard Monday-to-Friday schedule observing every federal holiday. Employers that skip Columbus Day and Juneteenth count 252.
2028 calendar quarters
| Quarter | Start | End | Days |
|---|---|---|---|
| Q1 | Saturday, January 1 | Friday, March 31 | 91 |
| Q2 | Saturday, April 1 | Friday, June 30 | 91 |
| Q3 | Saturday, July 1 | Saturday, September 30 | 92 |
| Q4 | Sunday, October 1 | Sunday, December 31 | 92 |
The leap day lengthens Q1 to 91 days, matching Q2. In a common year Q1 has 90.
2028 calendar week numbers
Under ISO 8601, week 1 is the week containing the year’s first Thursday. The first Thursday of 2028 is January 6, so ISO week 1 of 2028 begins on Monday, January 3.
Saturday, January 1 and Sunday, January 2, 2028 therefore belong to ISO week 52 of 2027.
At the other end, Sunday, December 31, 2028 is the final day of ISO week 52 of 2028. The year contains 52 ISO weeks.
2028 seasons and daylight saving time
| Event | Date | Time (Eastern) |
|---|---|---|
| March equinox, spring begins | Sunday, March 19, 2028 | 10:16 p.m. EDT |
| June solstice, summer begins | Tuesday, June 20, 2028 | 4:02 p.m. EDT |
| September equinox, autumn begins | Friday, September 22, 2028 | 7:45 a.m. EDT |
| December solstice, winter begins | Thursday, December 21, 2028 | 3:19 a.m. EST |
Daylight saving time begins at 2:00 a.m. local time on Sunday, March 12, 2028 and ends at 2:00 a.m. on Sunday, November 5, 2028, following 15 U.S.C. 260a as amended by the Energy Policy Act of 2005.
Every 2028 season begins a day earlier than its 2027 equivalent. Equinox and solstice instants drift about six hours later each year, then snap back roughly a day when a leap year inserts February 29.
The March equinox is the clearest case: 4:24 p.m. EDT on March 20, 2027, then 10:16 p.m. EDT on March 19, 2028 — six hours later in absolute terms but a calendar day earlier.
Frequently asked questions
Is 2028 a leap year?
Yes. 2028 has 366 days, with February 29 falling on a Tuesday. A year is a leap year if it is divisible by 4, except century years, which must also be divisible by 400. 2028 divided by 4 leaves no remainder.
How many working days are in 2028?
250, on a Monday-to-Friday schedule observing all federal holidays. The year has 260 weekdays and ten observed federal holiday dates, all of which fall on weekdays. Employers that skip Columbus Day and Juneteenth count 252.
Why does 2028 have only ten federal holidays?
Because New Year’s Day 2028 falls on Saturday, January 1, and its observance moved back to Friday, December 31, 2027. Under 5 U.S.C. 6103(b), a Saturday holiday is observed on the preceding Friday — which in this case sits in the previous calendar year. The statutory count remains eleven per year; only the calendar year of the observance changes.
