We’ve been recently tasked with building an interactive time zone picker for Date.Tools<\/a>, and surprisingly, there was no solid ready-made solution available online. So we created our own. We started with a public SVG world map from Wikimedia Commons<\/a>, stripped out unnecessary layers, and made it fully interactive using jQuery<\/a>. In this article, I’ll explain how we built it, with a live demo<\/a> included.<\/strong><\/p>\n

What are Time Zones?<\/h2>\n

Time zones<\/a> are regions that observe the same standard time, defined as an offset from Coordinated Universal Time (UTC). Offsets can include minutes (e.g., UTC−03:30, UTC+09:30) and may change seasonally where daylight saving time is used.<\/p>\n

Interesting Time Zone Facts<\/h3>\n
    \n
  • \nChina<\/strong>\u26e9\ufe0f uses one time zone, even though it spans five natural ones.\n<\/li>\n
  • \nNepal’s \ud83c\udfd4\ufe0f time zone is UTC+5:45<\/strong>, a rare 45-minute offset.\n<\/li>\n
  • \nKiribati \ud83c\udfdd\ufe0f adopted the world’s first UTC+14<\/strong> time zone in 1995.\n<\/li>\n
  • \nSamoa \ud83e\udd65 skipped December 30, 2011 by moving across the Date Line.\n<\/li>\n
  • \nSpain \ud83d\udc83\ud83c\udffd still uses CET, causing unusually late sunsets.\n<\/li>\n<\/ul>\n

    Demo<\/h2>\n
