About the time in Newcastle
The zone identifier America/Denver is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Denver keeps pointing at Denver time whatever the date, which is why every timestamp on this page is built from it.
Newcastle sits at latitude 37.67, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 20m is one point on that curve, not a fixed value.
If you are coordinating from another country, the shortcut is the working window: a normal Newcastle day of 09:00–17:00 falls between 15:00–23:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
