It is difficult to adjust to the time change in the spring.
In the spring, people lose an hour of sleep and they feel tired.
Lose an Hour
If you wake up at 6:00, it is like waking up at 5:00.
If you eat lunch at 12:00, it's like eating lunch at 11:00.
Everything seems earlier after you lose an hour in the spring.
Gain an Hour
If you wake up at 5:00, it is like waking up at 6:00.
If you eat lunch at 12:00, it is like eating lunch at 1:00.
Everything seems later after you gain an hour in the fall (autumn).
