Ananova:

Today is the happiest day of the year.

Experts found that people were more happy on May 18 because it is spring, the days are sunnier and longer and there is a Bank Holiday soon.

The most miserable day of the year is January 3 when thousands of people return to work after the Christmas break.

According to The Sun Skills minister Phil Hope said: "Spring is all about new beginnings. This time of year can give us all a renewed enthusiasm."
