4. Which Days Should You Avoid Trimming Your Nails?
In addition to choosing lucky days for trimming your nails, it’s also important to avoid certain days to prevent bad luck. According to the monthly nail-trimming calendar, the first day of each month is particularly inauspicious for this activity.
The 1st day of the lunar month is a time when yin energy dominates and yang energy weakens. According to folk beliefs, trimming your nails on this day can cut away part of your vitality, making your body weaker and more susceptible to negative energy. For business owners and traders, avoiding nail trimming on this day is crucial as it may negatively impact their business operations.

The 6th and 7th days of the month: These days are considered inauspicious in feng shui. Trimming your nails on these days may attract bad luck, disputes, health issues, or unexpected accidents. Therefore, it’s best to avoid cutting your nails during this time.
According to the nail-trimming calendar for lucky days, the 30th day of the month is also considered unlucky. In feng shui, the end of the month is a period of strong yin energy, and activities that affect your energy, like trimming nails, should be avoided. Doing so may lead to misfortune or, in severe cases, even endanger your life.
Additionally, regarding the question of whether you should trim your nails on New Year’s Day, the answer is no. The first day of the new year is a time to avoid cutting nails, hair, or washing your hair. Ancient beliefs suggest that losing any part of your body on this day may bring bad luck for the entire year.
Additionally, you should avoid trimming your nails in situations such as during exams, when you’re ill, or before facing an important event, as it may cause you to lose your good fortune.
5. What Is the Best Time of Day to Trim Your Nails?
Now that you know the best days for trimming your nails to attract good luck, what is the ideal time of day to do so?

A day has 24 hours, and the best time to trim your nails is during daylight, roughly between 6 a.m. and 6 p.m. The sun’s yang energy helps replenish the vitality lost during nail trimming. The exact timing may vary depending on the season, but as long as it’s daytime—whether sunny or overcast—it’s considered suitable.
Therefore, you should avoid trimming your nails at night to prevent exposure to yin energy. If you have a broken or chipped nail, only trim that specific nail and wait until daytime to trim the rest.
In this article, you’ve explored with Mytour the best days for trimming nails to attract good luck, the days to avoid, and the optimal time of day for this activity to foster positivity.
