Dr Cliff Arnall, a former Cardiff University lecturer, has revealed that June 18 is the happiest day of this year.
Dr Arnall based his prediction on complex mathematical calculations. He revealed that things like sunny evenings, blooming flowers, holiday anticipation and fond memories of childhood summers, which evoke feelings of happiness are at their peak today.
"Around 20 million people will watch England v Algeria on TV, and a win would mean millions being on a high even higher than is seen among most people at this time of year," The Daily Express quoted Dr Arnall as saying. "The third Friday in June came out with the highest rating due to peaking happiness factors such as warm summer evenings outdoors, seeing friends more frequently, and excitement about holidays."
