Why can my observed holiday date be different?

Weekend holidays, substitute days, collective agreements, and company policies can move the day you actually receive off. Add the date supplied by your employer as a Company Day Off before optimizing.

How are the 10, 15, and 20-day PTO results calculated?

They are generated by Holiday Optimizer's Balanced strategy for 2028, using a standard Monday-to-Friday workweek, the holiday dates on this page, and no pre-booked or company-specific days. Your personalized result can differ.

Hawaiʻi public holidays and PTO planner

This planning baseline starts with U.S. federal observed dates, then applies Hawaiʻi's source-reviewed state-government differences: it adds Prince Jonah Kūhiō Kalanianaʻole Day, Good Friday, King Kamehameha I Day, Statehood Day, and election-year closures. The exact dates below feed the same PTO optimizer used by the main planner.

Planning baseline—not an employer calendar. Confirm paid holidays and observed dates with your workplace before requesting leave.
