At 2 a.m. in the United States today (March 8), Daylight Saving Time (DST) will arrive and will bring with it an extra hour of daylight in the evening. That extra hour, however, needs to be ‘created’ by everyone in the U.S. setting forward the clock by an hour at 2 a.m. local time.

While analog watches need to be manually adjusted for DST, your Android smartphone or tablet is smart enough to automatically move the clock ahead by an hour when DST starts.

However, in certain cases your Android device might not move the clock forward by an hour. In such scenarios, you should try to restart your Android device and see whether it helps or not. In case that does not work as well, you can manually change the time by going to Settings -> Date & Time, removing the tick from ‘Automatic date & time’ option, and proceeding to manually enter the current time.

Do keep in mind though that you will have to manually change the time again when DST comes to an end.

Note: Some places in the U.S. do not observe DST including Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas. For European countries and the UK, Daylight Saving Time will start from March 29. In Australia and New Zealand though, the clock needs to be moved back by an hour on April 5th.
