The day always falls on the first Friday in April (this is not negotiable). The weather does not matter, the day must go on!
One's ankles must be showing. What one chooses to wear to display their ankles is left entirely to the discretion of the individual. Eligible participants include anyone.
If the weather is still cold, it is meant to prove that hope will prevail regardless! For those who have the joy to already be frolicking through warmer days, it is meant for the simple joy of celebrating their fortune in that warmer weather.
