Hawaii State Holidays 2028

Last reviewed: May 19, 2026 · Holiday data: June 23, 2026

Hawaii state government offices observe 12 holidays in 2028: the federal holidays plus 3 state-specific days (Prince Jonah Kuhio Kalanianaole Day, Kamehameha Day, Statehood Day). Banks and most private employers in the United States follow the federal calendar, so a standard business-day count is unchanged: 2028 has 251 federal working days.

How Hawaii's holidays differ from the federal set

Hawaii observes additional state holidays under the Hawaii Revised Statutes: Prince Jonah Kuhio Kalanianaole Day on 26 March, Kamehameha Day on 11 June, and Statehood Day on the third Friday of August. These are Hawaii state-office closures. Banks and most private employers follow the federal calendar, so the working-day total uses the federal holidays and is not changed by these state days.

State holidays beyond the federal set (2028)

  • Prince Jonah Kuhio Kalanianaole Day (Sunday, March 26)
  • Kamehameha Day (Sunday, June 11)
  • Statehood Day (Friday, August 18)

Effect on business-day counts

The working-day total on this page uses the federal holidays that banks and the Federal Reserve observe nationwide. The Hawaii holidays listed here are state-government office closures; most private employers do not close for them, so they usually do not change a business-day count. Observed dates can shift when a state holiday falls on a weekend.
