Spring is almost here, and so is Daylight Saving Time (DST).
Before you go to bed this Saturday, March 12th, please move your clock one hour forward . For example, at 8 pm on Saturday, change the clock to 9 pm.
If you are concerned about the adjustment, you can spread it out into chunks. For example, starting on Wednesday, go to sleep 15 minutes earlier each night. For more tips, please have a look at Daylight Saving Time 2015: How the time change affects your internal clock.
