Here are two answers:
First, this process is known as Daylight Savings Time, which affords most people more sunlight during the daylight hours.
Second, it takes place at 2AM, apparently, because there are fewer people awake at that hour, so the impact is less severe. For example, in the spring, there is no 2AM hour: from 1:59AM the next minute is 3AM. And in the fall there are two 2AM hours: from 2:59AM, the next minute is 2AM.
I would assume to avoid any confusion as to the date. 2am would prevent the date from changing backward which would occur if you set the change time at midnight. It would only be rational to pick a time that would have the least conflict with the largest number of citizens and businesses. Other than that, I would assume it is an arbitrary time which probably drew the least objections.
In Daylight Saving Time, you turn your clocks forward in the spring and backward in the fall.
Remember to "spring forward, fall back" for daylight saving time. In spring, set the clock forward one hour; in fall, set it back one hour. This phrase helps you remember which way to adjust your clock.
The opposite of "spring forward" is "fall back," which refers to the practice of setting the clocks back one hour in the autumn when daylight saving time ends.
Daylight saving time typically starts in the spring and ends in the fall. In most regions, clocks "spring forward" in the spring and "fall back" in the fall.

You turn the clock forward in the spring for daylight saving time, usually on the second Sunday in March. You turn the clock back in the fall for standard time, usually on the first Sunday in November.
You loose an hour when clocks go forward. For example if you get up every day at 6am, after the clock change it really will be like getting up at 5am. You lost 1 hour at 2am, it will probably be darker where you are now in the morning. On the bright side of things, we get an extra hour of daylight.
Clocks in england change twice a year to equate British summer time. They go forward one hour at the end of March (spring) and go back one hour at the end of October (fall) hence the saying 'spring forward, fall back'
There is not a set date for either of these times. Nevertheless, they follow the rule that the last Sunday in March the clocks go forward. The last Sunday in October the clocks go back. This can be remembered with the mnemonic "the clocks spring forward in spring and fall back in fall"
The American law by which we turn our clock forward in the spring and back in the fall is known as the Uniform Time Act of 1966.
