L'ora Legale or Daylight Saving Time (DST) in English for this year was imposed officially at 25 March. DST also known as Summer Time.
In DST, people all over Europe and some part of United States adjust their time 1 hour earlier than the 'true' time. This due to reason to save the energy, where the daytime is longer than night time.
It changes the time at 02.00 AM to 03.00 AM on last Sunday of March. And the time will back to normal time (l'ora solare) from 03.00 AM to 04.00 AM on last Sunday of October.
Since I'm from tropical country, which has the same range of day time and night time, this is an unusual phenomena. Then, I decided to record this :D
I showed also this video to my European friend, and they amazed about this phenomena. They even haven't seen this.
buon primavera! Happy spring
