The specific dates when Daylight Saving Time begins and ends, and the amount of time that the clock is adjusted, can vary depending on the location. The purpose of Daylight Saving Time is to make better use of the available sunlight during the longer days of the summer by shifting some of the daylight from the morning hours to the evening hours. This is done by moving the clock ahead by one hour at a specified time in the spring and then moving it back by one hour at a specified time in the fall. In the context of time zones, “summertime” typically refers to Daylight Saving Time ( DST), which is the practice of setting the clock ahead by one hour during the summer months in order to extend the amount of daylight in the evenings. Some areas, such as parts of India, Iran, and Australia, use non-standard half-hour deviations. For example, China could be divided into several time zones, but instead, the whole country uses the same time. Thus, for convenience, entire countries tend to adjust to the same local time rather than adjusting exactly to the zones. Governments can change their country’s time zone. The zones were measured according to the Greenwich Mean Time, used as the starting meridian, which measured hours before and after GMT. There are 24 timezones, separated by one-hour intervals, with each 15 degrees longitude. If someone travels by plane between two zones, he or she will adjust his/her clock to the one used in the new zone. Within each zone, people set their clock for the same time. This is because we divide the earth into different time zones. When it is noon in Rio de Janeiro, it is midnight in Tokyo.
