International date line Time

What should I do to account for the International Date Line and the time differences for 5 schoolchildren?

Next thing to be understood is the discrepancy between live and offical time at any location. It is my belief that children can readily comprehend that" a few moments or even one or two hours off the clock is less important than the discomfort of having to alter the time each time you move a little to the western or eastern direction.

In this way we draw 24 north-south strips on a card and allocate the same time to all points within a strip. Whereas time bands *should* be displayed as perpendicular bars on this chart, they don't do so for the added comfort of being able to allocate the same time band to areas that are political and economic "close", so you don't have to think about time difference when you call or travel.

The last issue is the international dateline. To explain this line is more complicated and less intuitively. On the basis of all this, the children should already realize that the "local time" changes when you go westward or eastward. It is already 6am (the next day!) in Beijing, China at 12pm in Vienna, Austria and it is still 6pm in Washington DC.

How does the International Date Line come into it? Here's the trouble (from https://en.wikipedia.org/wiki/In...): A man who rounds the worid from left to right (the same way as Magellan's journey) would reset his watch one minute per 15 degrees of intersection, and he would win 24 hrs for a round of the earth from left to right if he didn't move his watch one extra minute forwards when he crosses the IDL.

Therefore, the IDL must be considered in connection with the time zone of the earth: When traversing in both directions, the date of the calendars is adapted by one date. That is, the time changes constantly when you go eastward or westward, but the results are that the watch is gradually right, but the date is inaccurate.

All of them set the watch while he or she is walking. If they met halfway (+) across the globe, one of them turned back the watch by 12 and the other by 12 hours resulting in a net 24-hours-variation.

The international time line is therefore a line whose traverse must be offset by +/- 24h. Obviously (*) nobody wants to have such a line in a place where he or she has to often traverse, and nobody wants a days of differences with his or her main business mate.

Therefore, a policy was decided to place such a line in the center of the largest oceans, where few humans are living and crossing even less and not in the center of Asia, Europe or America or in the center of the Atlantiks, which was (and still is) a very lively "street" at the time of the foundation of the line.

Kiribati's recent significant change to the International Date Line was heralded by the Kiribati administration in 1994. The International Date Line, which for historical purposes divided the archipelago into two parts, was long regarded as an annoyance to the economy. Occidentally, the west of the country was always 24hrs ahead of its east, and there were only four trading sessions a day a week between them.

In order to put an end to this problem, Teburoro Tito (the Kiribati State Secretary and Chairman from 1994 to 2003) said that on 1 January 1995 the International Date Line would run along the multi-faceted border to the east of the State. If they don't get together halfway, one will winder the watch by +10 and the other by -14 or so.

Net amount is always 24h. There is a time lag of three days between two places close by, which means a three-day week-end for anyone who wants to do a deal during such a time.
