IANA Timezone Regions

IANA Timezone Regions represent the top-level classification in the Time Zone Database managed by the Internet Assigned Numbers Authority (IANA). This database collects and maintains historical information about standard time zones worldwide, organized into 11 primary regions (Africa, America, Antarctica, Arctic, Asia, Atlantic, Australia, Europe, Indian, Pacific, and Etc). Each region is structured based on continents or oceans, with specific city or location timezones nested underneath.
