Are you confused how does daylight saving effect time?
Historically, DST that is daylight saving time started in the months of summer and ended in winter, but the dates of DST have changed with time as the U.S. government has passed new laws, according to the USNO- U.S. Naval Observatory.
It was started in 2007 in the United States in March of the second Sunday. People push their clocks forward an hour at 2 a.m. according to LST-local standard time.
On the first Sunday of November, the daylight saving time ends, and the clocks are moved back an hour at 2 a.m. according to local daylight time. This year that is in 2018, DST begins on 11th March 2018 and ends on 4th November 2018. So you have to move your clock an hour forward on March 11, 2018. Last year that is in 2017, DST started on 12th March and ended on 5th November.
So if we talk in simple words, then we lose an hour when Daylight Saving Time (DST) begins, and we gain an hour when it ends.
Skip an hour in spring:
DST starts in the spring and at the time of starting we set our clocks forward by a fixed amount of time, mainly by 1 hour. So an hour skipped from the schedule, and the starting day of DST has only 23 hours. Most of the time, DST switches occur at night to avoid disturbing public life. But it steals away an hour of sleeping time, and it requires us to adjust biological body clocks. With altering time.
Example of DST Start:
In the United States, The DST period starts at a local time of 02:00 am, so the hour starting from 2:00:00 to end 2:59:59 does not exist in the night of the DST. This DST changes skipped the spring clocks forward from 1:59:59 am (standard time) to 3:00:00 am (Daylight Saving Time).

clocks jump ahead by 1 hour
In the different countries the DST period may begin and end at different local times but the principle of changing time remains the same.
Repeat an Hour in Fall
The DST period usually ends, in the autumn and it is time to set back the clocks to standard time again. Regarding local time, we get 1 hour extra and the day DST end changes into 25 hours.
In conclusion, 1-hour reappear as local time leaps back from DST to standard time and we can say that the clocks come behind from 2 am to 1 am. In another word the hour between 1 and 2 am appears twice during the night DST ends.
Example of DST End
In the US, DST always ends at 02:00 am according to local time, and clocks are arranged back to 01:00 am. From the below table you can see that the moment when the time first reaches 1:59:59 and clocks revert to 1:00:00 standard time and begin ticking towards 2 am for the second time. When the repeated hour is over, local time goes from 1:59:59 to 2:00:00, just like any normal day.
