Time converter tool

It occurs in Canada and the United States and moves the clocks forward by one hour in the warmer summer months to allow for more extended daylight. The clocks are then turned back one hour in the fall, allowing for a shorter period of sunlight during the colder months. Time zones were created because when clocks were first invented, most places set their clocks based on the sun's rising and setting—creating time zones allowed each different region to mark their time based on the rising sun.

Each degree of longitude on the globe marks a four-minute difference of time as determined by the sun's position on the earth, meaning that the sun will have just risen at one location. Simultaneously, at the following longitudinal line, the sunrise will not take place for another four minutes.

Time and specific time zones also became extremely important with the rise of the railroad. Having trains that ran on time and whose arrival could be accurately determined created further need for strict time guidelines.

UTC stands for universal time coordinated, and it is the global time and date that all clocks and time zones are set against. It is a common misconception that the time zones around the world follow the globe's longitudinal lines. Most time zones follow country borders and land boundaries instead. This makes it much easier for political and business communications to occur without concern for time differences.

The first two fields are the current date and time and you can change according to your needs. Below are two lines in which you need to choose the starting point for the international time conversion and the location for which you want to find the corresponding time. In each of the two lines you first need to choose the region in order to narrow your choice. Once you have selected the region the second selection for location will display the countries or the cities in the region you chose in alphabetical order for you to find the desired place easier.

As you press calculate the time zone converter will find your locations in a complex database of the world time zones, check whether it needs to take into consideration the existence of a daylight savings time and will then calculate the time zone difference between your two locations and return you with the exact time in the second place you chose.

Surprisingly enough there are many situations in which you can find yourself in need for a quick check of an international time in a given place and the easiest way is to use such a tool. Maybe you are going on a vacation in a foreign place and want to know exactly the local time there or you need to call someone overseas. You can even find yourself in the situation to make phone calls or conferences abroad and you need to schedule them at an appropriate time for all the participants and the biggest the time difference is the harder will be for you to manage things without knowing exactly the local time there.

Also knowing important world time zones can help you make connections between time and geographical position of certain countries making it easier for you to remember where some place is or simply check how the daylight savings time system works in other places. This represents the modern civil time and has been defined since January to follow the International Atomic Time TAI with an exact offset of an integer number of seconds. This time keeping method is less exact than the UTC because the rotational period of Earth is not perfectly constant and the duration of a second would vary if calibrated to a telescope-based standard like GMT.

A UTC time offset is the amount of time subtracted from or added to UTC to get the current local time for a specific location. Time Zones define the geographical regions that observe a certain standard time. By convention, every time zone computes local time as an offset from UTC.

DST, also known as summer time represents the practice of advancing clocks in the summer months so that afternoons have more daylight and so electricity costs would be reduced. The one hour shift occurs at local time shifts to local time in spring and from to in autumn. Each country has established dates in which to make the switches for the following years. Northern and southern hemisphere countries are the ones that use in a larger number DST while near equator DST is not that used because sunlight changes are minimal there.

Daylight Saving Time begins at a. The table below shows the nine standard time zones in the United States, their corresponding DST time zones and the states that follow that.
