What does the number 13 mean?

13 stands for a lifetime, 13 roses stand for everlasting friendship! "13" has always been considered as an unlucky number. This tradition may be related to the creation of the early lunar calendar method, which can be traced back at least to the time of Hersius (700 BC). The thirteenth day of each month in a year is not suitable for sowing. It is said that Satan ranks thirteenth in the witch's spell, and the thirteenth card of Tarot represents death. However, in Central America, the number "13" is extremely sacred, because in the local indigenous religious calendar, there are thirteen days in a week.
