Another example is Vorkuta in Russia, where sunrise and sunset annually average out at 4:40AM and 4:40PM – with "yesterday" sunrises in May and July. As an example: in the American Eastern Time Zone, Boston and parts of Maine and New England, see daybreak around 4:45–5:45AM in the summer and sunset by 8PM, but in the western edge, Indiana Michigan, sunrise isn't until 6:30AM and it isn't dark til 9:15–10:15PM. As such, it might be a good idea to check sunrise and sunset times for the time of year you'll be travelling to your destination. Sunrise and sunset can occur at vastly different times than you might be used to, varying from east to west across each time zone. Darkness comes soon after sunset near the equator, while real dusk comes half an hour after sunset at latitudes of 60°. The hottest time is usually the hours after noon. If you don't have these times available, note that the sun moves 15° of longitude by hour, so 30° east of Greenwich, the sun is at its highest at 10:00 UTC if the time zone is UTC+1, that's 11:00. Often the only thing that matters is wall clock time, but in areas where you'd prefer indoor activities in the hottest hours, or where daylight hours are few, check times of the hottest hours, the hours with most UV-radiation, or times of sunrise and sunset, depending on your needs. While when observing "sun time", the sun is at its highest at noon, the political time zones can be stretched out or biased to differ even a few hours from this. Map showing the difference between clock time and solar time (ignoring DST) The total span of time zones covers more than 24 hours because the Date Line jogs westward and eastward to keep certain national island groups on the same calendar day, although they are not within a single time zone. Crossing the Date Line going eastward, clocks are turned back a full 24 hours, and vice versa in the opposite direction. UTC+4) zones west of UTC and east of the Date Line are specified by the number of hours behind UTC (e.g. Time zones east of UTC and west of the International Date Line are specified by the number of hours ahead of UTC (e.g. It comes from the nautical system in which each time zone was assigned a letter. The "Z" is for "zero", and "Zulu" is the two-way radio pronunciation of "Z". UTC is also sometimes called Z or Zulu time. GMT (Greenwich Mean Time) is nearly synonymous, named after the Royal Observatory located in the Greenwich area of London, but its definitions have varied over time and may vary slightly by context. Like as the waves make towards the pebbled shoreĪlthough many time zones have descriptive names used by people in them, they are least ambiguously identified by their relationship to UTC (Universal Time, Co-ordinated). For extreme sunrise and sunset times, occurring in the far north and south, see also Midnight sun. Below is also a list of countries, regions, and territories grouped by time zone. This article discusses most of those issues. The official local time affects opening hours, but for outdoor activities you may need to also consider when it is morning or noon according to the sun. Watches and smartphones may show a time different from the local one, friends may call in the middle of the night as it is afternoon at home, and the sun may rise at wall clock times you wouldn't expect. Time zones and daylight hours affect travellers in many ways.
