Nail Trimming
Trimming fingernails and toenails. In the old days, the first time a baby's nails were cut required choosing a specific day.
'Nail trimming' refers to cutting fingernails and toenails. This practice appears in almanacs because, traditionally, the body—including hair and skin—was considered a gift from parents, so the act of cutting it off required choosing an auspicious day, similar to getting a haircut or shaving the head.
The most common usage involves the first nail trimming for an infant around the time of their full-moon celebration. In the past, this was seen as the child's first act of 'removing' something from their body, making it a particularly solemn occasion. Families would often avoid days marked as inauspicious on the almanac.
While modern practice rarely involves choosing a day for this, in families that maintain strong traditional customs, the first shaving of an infant's lanugo and the first nail trimming are often planned together for a specially chosen day.
