Hawaii State Holidays 2028

Last reviewed: October 14, 2026 · Holiday data: September 11, 2026

Hawaii's own holiday calendar for 2028 is listed below under the Department of Human Resources Development schedule, next to the federal holidays this page counts. The business-day total follows the federal list in 5 U.S.C. 6103, taking each holiday on the day federal employees have it, and gives 2028 250 working days; Hawaii's own days are marked in the table and never subtracted.

How Hawaii's holidays differ from the federal set

Hawaii's state holidays, as the Department of Human Resources Development lists them in its holiday schedules, add the state's own days to the federal list: Prince Jonah Kuhio Kalanianaole Day on 26 March, Good Friday, King Kamehameha I Day on 11 June, Statehood Day on the third Friday of August, and the general election day in even-numbered years. Juneteenth and Columbus Day are not Hawaii state holidays. State agencies observe a Saturday holiday on the Friday and a Sunday one on the Monday, as the same schedules show.

After 106 weekend days and 10 weekday federal holidays, 2028 has 250 working days on the federal count. Hawaii's own holidays are not subtracted; the section below shows how its calendar would change the total.

Federal Reserve and FedACH counts around Saturday holidays

This calendar combines federal and Hawaii holidays, and its business-day count takes each federal holiday on the day federal employees have it. When a holiday falls on a Saturday, 5 U.S.C. 6103(b) makes the Friday before it the legal public holiday for employees whose basic workweek is Monday through Friday (the Office of Personnel Management says the same of most federal employees, for pay and leave purposes), so this page's count leaves that Friday out. The Federal Reserve Banks are open that Friday. A count on the Reserve Banks' schedule, which the same page sets out for FedACH, therefore has one more business day across one of those Fridays than this page's count shows. Whether Hawaii also treats that Friday as a holiday is a separate question, settled by its own holiday rules.

Fridays this affects in 2028:

  • Friday, November 10, 2028 (Veterans Day falls on Saturday, November 11, 2028)

Hawaii in 2028: how the calendar falls

Every figure below is computed from the 2028 dates in the table above and the Monday to Friday week, and each rule names the provision or the official list it is taken from. When a date changes, the sentences change with it.

Hawaii's state holidays in 2028

The holiday schedules of Hawaii's Department of Human Resources Development (DHRD) list each state holiday beside its "Official Date Designated in Statute/Constitution". The holidays they list that are not federal holidays are Prince Jonah Kuhio Kalanianaole Day (the twenty-sixth day in March), Good Friday (the Friday preceding Easter Sunday), King Kamehameha I Day (the eleventh day in June), Statehood Day (the third Friday in August) and, in even-numbered years, General Election Day. The schedules list neither Juneteenth nor Columbus Day.

The Department of Human Resources Development publishes the dates state agencies observe, and its schedules show a Saturday holiday on the Friday before and a Sunday one on the Monday after. In 2028 they show Prince Jonah Kuhio Kalanianaole Day on Monday, March 27 instead of Sunday, March 26, King Kamehameha I Day on Monday, June 12 instead of Sunday, June 11, and Veterans Day on Friday, November 10 instead of Saturday, November 11.

Good Friday is Friday, April 14 in 2028. The DHRD schedules list it and the federal list does not, so this page's count treats it as a working day.

2028 is an even-numbered year, and the DHRD schedules list General Election Day for it: Tuesday, November 7. They give its date as the first Tuesday in November following the first Monday of even-numbered years and cite Article 2, Section 8 of the Hawaii State Constitution.

Why Hawaii gains working days in 2028

A year's working days are its weekdays minus the holidays that land on them, and both halves move. The weekday supply depends only on the year's length and the weekday it starts on; the holiday half depends on where each fixed date falls that year. 2028 is a leap year that opens on a Saturday, so its two days beyond 52 whole weeks are a Saturday and a Sunday. It ends up with 260 weekdays, fewer than an ordinary year that starts midweek.

Ten federal holidays in this page's count fall on weekdays, so Hawaii has 250 working days in 2028. That is one more than 2027 (249). That happens against the calendar, which supplies one fewer weekday; the holidays decide it, with two fewer of them on weekdays.

Saturday and Sunday holidays in 2028

A fixed-date holiday on a weekend is where the federal, Reserve Bank and state calendars part company. For most federal employees a Saturday holiday moves to the Friday and a Sunday one to the Monday (5 U.S.C. 6103(b) and Executive Order 11582, as OPM applies them); the Federal Reserve Banks follow the Monday rule but not the Friday one; and Hawaii has its own rule. In 2028:

  • Prince Jonah Kuhio Kalanianaole Day (observed) falls on Sunday, March 26, and Hawaii state agencies observe it on Monday, March 27.
  • King Kamehameha I Day (observed) falls on Sunday, June 11, and Hawaii state agencies observe it on Monday, June 12.
  • Veterans Day falls on Saturday, November 11; most federal employees have Friday, November 10 as the holiday instead. The Federal Reserve Banks are open that Friday; the Board of Governors is closed. Hawaii state agencies observe the holiday that Friday too, as the DHRD schedule shows.

This page's count leaves out the Friday or Monday that federal employees have as the holiday, because the count follows the federal employees' holidays. A count on the Federal Reserve Banks' schedule has one more business day across each of those Fridays.

Where Hawaii's own calendar departs from the count in 2028

The count on this page and Hawaii's state-agency calendar (the DHRD holiday schedules) differ only where one of them has a holiday on a weekday and the other does not. The Hawaii calendar has Prince Jonah Kuhio Kalanianaole Day (observed) on Monday, March 27, Good Friday on Friday, April 14, King Kamehameha I Day (observed) on Monday, June 12, Statehood Day on Friday, August 18, and General Election Day on Tuesday, November 7 as holidays, which the federal count treats as working days. The federal count takes out Juneteenth on Monday, June 19 and Columbus Day on Monday, October 9, which the Hawaii calendar does not.

On balance the Hawaii calendar has 247 working days in 2028, three fewer than the 250 this page counts.

Where the fixed-date holidays land in 2028

A holiday tied to a calendar date moves one weekday later each year, and two once 29 February has passed, so the week it breaks changes every year while its date stays put. 2028 is a leap year, so every date from March onward jumps two weekdays against 2027:

  • New Year's Day is a Saturday in 2028, after a Friday in 2027, a weekend day, so the date itself takes no working day on this page's count; the weekend rules above decide whether a weekday is given for it.
  • Prince Jonah Kuhio Kalanianaole Day is a Sunday in 2028, after a Friday in 2027, a weekend day, so the date itself takes no working day on the Hawaii calendar; the weekend rules above decide whether a weekday is given for it.
  • King Kamehameha I Day is a Sunday in 2028, after a Friday in 2027, a weekend day, so the date itself takes no working day on the Hawaii calendar; the weekend rules above decide whether a weekday is given for it.
  • Juneteenth is a Monday in 2028, after a Saturday in 2027, so on this page's count it turns the weekend before it into three days off.
  • Independence Day is a Tuesday in 2028, after a Sunday in 2027, which strands Monday, July 3 between the weekend and the holiday on this page's count.
  • Veterans Day is a Saturday in 2028, after a Thursday in 2027, a weekend day, so the date itself takes no working day on this page's count; the weekend rules above decide whether a weekday is given for it.
  • Christmas Day is a Monday in 2028, after a Saturday in 2027, so on this page's count it turns the weekend before it into three days off.

Eight long weekends in 2028

A weekday holiday next to a weekend turns two days off into three; two closures side by side, or one on each side of a weekend, make four or more. That is arithmetic on the dates, so the list moves every year even when the holidays do not. On this page's count, Hawaii has eight such breaks in 2028:

  • Saturday, January 15 to Monday, January 17: three days, for Martin Luther King Jr. Day.
  • Saturday, February 19 to Monday, February 21: three days, for Presidents' Day.
  • Saturday, May 27 to Monday, May 29: three days, for Memorial Day.
  • Saturday, June 17 to Monday, June 19: three days, for Juneteenth.
  • Saturday, September 2 to Monday, September 4: three days, for Labor Day.
  • Saturday, October 7 to Monday, October 9: three days, for Columbus Day.
  • Friday, November 10 to Sunday, November 12: three days, for Veterans Day (observed).
  • Saturday, December 23 to Monday, December 25: three days, for Christmas Day.

On the Hawaii calendar the breaks differ: Saturday, March 25 to Monday, March 27 (three days), Friday, April 14 to Sunday, April 16 (three days), Saturday, June 10 to Monday, June 12 (three days), and Friday, August 18 to Sunday, August 20 (three days). Those follow the state's own holidays and do not change this page's count.

Stranded working days in 2028

A holiday on a Tuesday or a Thursday leaves one working day stranded between it and the weekend. In 2028 Hawaii has two: Monday, July 3, next to Independence Day and Friday, November 24, next to Thanksgiving Day. Each is a full working day on this page's count even though a day off sits on either side, so a deadline that lands on one is not pushed anywhere.

Hawaii month by month, 2028

A month's working days are its weekdays less the holidays on them, so a month with no weekday holiday is set entirely by how its weekdays fall, and every holiday that lands midweek takes one day off the month it sits in.

The second column follows the federal set this page counts. The third follows Hawaii's state-agency calendar (the DHRD holiday schedules), for readers dealing with that calendar directly.

Hawaii's longest stretch without a holiday, 2028

The longest run of working days with no weekday holiday inside it depends on how far apart consecutive closures sit, so it moves whenever one fixed-date holiday changes weekday. In 2028 it runs from Tuesday, February 22 to Friday, May 26 inside the first half of the year: 69 working days, 13 full working weeks and four days.

The first working day of 2028 on this count is Monday, January 3, because 2028 opens on a weekend. The last is Friday, December 29, which is the latest date a count of working days can end on inside 2028.

Which calendar the 2028 count uses

The working-day total counts the legal public holidays of 5 U.S.C. 6103 on the dates most federal employees have them, as OPM publishes them. It is not identical to the Federal Reserve Banks' calendar. The Board of Governors' K.8 schedule states that the Federal Reserve Banks are open on the Friday before a Saturday holiday, and in 2028 that means Friday, November 10. A count on the Reserve Banks' schedule has one more business day across that Friday than this page's count shows.

Hawaii's state-agency calendar (the DHRD holiday schedules) is shown in the table and never subtracted from the count.

Hawaii 2028 FAQ

Do Hawaii's own holidays change the business-day count on this page?
No. The count uses the federal holidays in 5 U.S.C. 6103, each on the day federal employees have it.
