How international accuracy is handled

  1. Use named IANA zones instead of assuming a permanent abbreviation or fixed offset.
  2. Use the selected event date so daylight-saving rules apply to that date.
  3. Keep every language on its own URL with reciprocal hreflang and a self-canonical.
  4. Let visitors choose a language without redirecting by IP or browser language.
  5. Label weekend and public-holiday assumptions because they differ by country and authority.
