Saint Piran March 5

St Piran's Day began as one of many tinners' festivals observed by Cornish tin miners. Other miners' holidays of a similar nature include Picrous Day and Chewidden Thursday. The miners of Breage and Germoe observed St Piran's Feast Day as that of their patron saint until at least 1764.

The day of St. Piran was said to be a favorite of the tinsmiths who, having a tradition that certain secrets concerning the manufacture of tin were communicated to their ancestors by this saint, they let the manufacture move on for her- even for this day and keep it as a holiday.

There are few descriptions of specific traditions associated with this day aside from the consumption of large quantities of alcohol and food during "Perrantide", the week leading up to March 5. The day after St Piran's Day was known by many as 'Mazey Day', a term which has now been adopted by the revived Golowan Festival in Penzance. The phrase "drunk as a Perraner" was used in 19th-century Cornwall to describe people who had consumed large quantities of alcohol.
