Daylight Saving Time 2018

 from WikiMedia Commons

So, when exactly do we reset our clocks? And is it forward or backward one hour?

Daylight Saving Time can be very confusing. First of all, the very phrasing is often confused: it's Saving not Savings. We are saving daylight not putting something in a savings account. Read below to help end your confusion! [The chart on the left plots the times of sunrise and sunset (with DST adjustment as separate lines) in Greenwich, GB for 2007.]

Short answer
For the Spring- On Sunday, 11 March, 2018 at 2:00am, you should set your clock forward one hour to 3:00am.

For the Fall- On Sunday, 04 November, 2018 at 2:00am, you should set your clock backward one hour to 1:00am. (Remember "spring forward, fall back...").

Easy answer: Most people who go to bed earlier than the wee hours of the morning simply set their clocks back/forward one hour before they go to bed on Saturday.

Tryptophan & turkey

Eating turkey on Thanksgiving makes you sleepy because of the high levels of tryptophan (one of the nine essential amino acids) in the meat, right?? Most likely not.

While the conclusive verdict is still out, a little critical thinking and knowledge of food chemistry, physiology, and psychology reveals that the carbohydrates and relaxation of usual restraints during the holiday have more to do with the drowsiness than the turkey. In fact, cheese has more tryptophan in it than turkey and other meats like beef and chicken have about the same amount.
