WhatDay365, a little discovery every day

An ordinary day can be special to someone. WhatDay365 helps you discover observances and their meanings.

What kinds of days are included?

We cover Gregorian and Korean lunar observances, solar terms, folk traditions and Buddhist observances. Date rules and verifiable sources are shown. An observance is not necessarily a public holiday.

Some dates are not listed yet

Solar terms, Hansik, Sambok, Singugan and substitute holiday dates are available for 2020–2050 in Korea Standard Time. Son-eomneun days use Korean lunar dates, including leap months.

No listing does not mean there are no observances. Korean lunar dates are converted for Gregorian dates from February 13, 1000 through December 31, 2050, including the Seollal and Chuseok holiday periods.

Substitute holidays are calculated from listed public holidays. Temporary holidays and election days may vary with separate designations.
