HIHawaii Fun Facts

Capital: Honolulu ยท West ยท Admitted 1959

Hawaii is the only state that is physically still getting bigger. Kilauea's 2018 eruption in lower Puna filled Kapoho Bay and added more than 800 acres of brand new land to the island of Hawaii. Almost everything else about the state breaks a rule too, from its alphabet to its clocks to its highway numbering.

Geography that surprises

Where the name comes from

Hawaii takes its name from its largest island. Hawaiian tradition credits Hawaiiloa, the navigator said to have found the islands, while linguists connect the word to Hawaiki, the ancestral homeland named across Polynesia from Samoa to New Zealand.

In Hawaiian the word carries an okina, the glottal stop that also appears in Oahu and Kauai. The okina is a full letter in an alphabet of five vowels and seven consonants, one of the shortest alphabets in active use. Official English spelling drops it, which is why the same place name shows up two ways on road signs.

Frequently asked questions

What is Hawaii known for?

Hawaii is the only US state made entirely of islands, the only one with a royal palace, Iolani Palace in Honolulu, and the only one with two official languages, English and Hawaiian. It is also the only state with a continuous commercial coffee industry, centered on the Kona district of the island of Hawaii, and the only state that keeps growing as Kilauea erupts.

Why does Hawaii have two official languages?

The 1978 state constitutional convention made Hawaiian co-official with English. That reversed an 1896 law that pushed the language out of schools by requiring English as the medium of instruction. Hawaiian immersion schools reopened in the 1980s and the language is now taught from preschool through university.

What is the weirdest law in Hawaii?

Billboards have been banned in Hawaii since 1927. Hawaii is one of only four states, along with Vermont, Maine and Alaska, that prohibit them outright, which is why the highways carry no roadside advertising.

Is Hawaii still growing?

Yes. The 2018 Kilauea eruption in lower Puna poured lava into Kapoho Bay and added more than 800 acres of new land to the island of Hawaii. A separate underwater volcano, Kamaehuakanaloa, is building southeast of the island.

Why is Hawaii time different from the rest of the US?

Hawaii sits in the Hawaii Aleutian time zone and has not observed daylight saving time since 1967, so the gap with the West Coast changes twice a year: two hours behind in winter, three hours behind in summer.
