Methodology

Time-zone calculation

Every location on the site is tied to an IANA time-zone identifier such as America/New_York or Asia/Tokyo. The displayed local time and countdown to the next 5 PM are calculated in the browser using that zone identifier rather than relying on a manually updated timestamp.

This allows the clock to continue running after a page loads and helps preserve accuracy when daylight saving changes occur.

Location selection

The directory focuses on capital cities, widely recognised reference cities, and a small number of time-zone placeholders used to illustrate remote UTC offsets. The goal is coverage across the global clock rather than exhaustive travel listings.

Some countries share a time zone with other nearby locations, so the site uses a single reference page where appropriate. The pages are intended to help users compare time, not to function as formal travel or legal guides.

Editorial notes

Each city page includes a short greeting and a lightweight place note to make the page more useful than a bare countdown. These notes are written as concise cultural context. They are not intended to be exhaustive or authoritative country profiles.

Where a supplied note would be too legalistic, too promotional, or too thin to add value, the page falls back to neutral explanatory copy about the city, its reference role on the site, and its time-zone position.

Site updates

Supporting pages such as the About, Privacy, Contact, Methodology, and Editorial Policy pages are maintained to explain ownership, data usage, and review standards. These pages exist so users and reviewers can understand how the project works.
