We are talking about 5 and 27 lunar days. In May 2023, these days fall on the 18th (27th lunar day of the current cycle) and the 23rd (5th lunar day of the next cycle).
If this time is not convenient for you to go to the hairdresser, but you still do not want to violate the recommendations of the lunar calendar, you can choose other periods. For example, it is believed that the 14th day of the lunar cycle multiplies all good things in life – it falls on May 4, 2023. And 21 and 22 lunar days have a positive effect on a career. This month, these days will fall on May 11 and 12.
