I’m not superstitious but there are many that are so I gathered this information for you. Enjoy your scary day.
I wish there was a photo of the Catacombs in Paris, France on my computer, those are creepy and you can tell by the expression on my face it felt weird being with thousands of centuries-old human remains.
Friday the 13th is considered an unlucky day in Western superstition. It occurs when the 13th day of the month in the Gregorian calendar falls on a Friday, which happens at least once every year but can occur up to three times in the same year. For example, 2015 had a Friday the 13th in February, March, and November; 2017 through 2020 had two Friday the 13ths each, and the years 2021 and 2022 will both have just one occurrence each.Wikipedia
Interesting enough I found alternative thinking.
For centuries, Friday the 13 th was considered the day of the goddesses. It was the day to recognize and celebrate the divine sacred feminine and the cycles of endings and beginnings, death and birth that she inherently represents. Friday the 13 th was in essence a day to celebrate the feminine aspects and souls always present in our lives. Elephant Journal
Have a great day!
