everyday beliefs and customs
Why do Hindus not cut nails or hair on certain days of the week?
What the belief is
In Hindu tradition, each day of the week is linked to a planet and a deity. Saturday is ruled by Saturn, and Tuesday by Mars. These days are often seen as inauspicious, meaning not favourable for certain activities. Hair and nail cutting are thought to be things best avoided on these days. The belief is that cutting on an unlucky day might bring bad luck or misfortune. Some families also avoid cutting on other days depending on their region or family custom. The practice is described in old texts on daily life and custom, such as the Dharmasindhu.
Where it comes from
The roots lie in an old system of linking the days to planets and their energies, called Graha influence. This system is part of Hindu astronomy and astrology. Over time, folk belief turned these planetary associations into everyday rules about what is safe to do on each day. Different regions and communities developed their own versions of which days to avoid. The exact reasons have been debated and explained in many ways over the centuries.
In everyday life today
Some families keep this custom strictly, planning haircuts and nail trimming for auspicious days. Others follow it loosely or not at all. In cities and among younger people, the practice is less common, though many still avoid Saturday or Tuesday out of habit or respect for what their parents did. The custom varies widely by region, family background, and how traditional a household is. Abroad, where salons may not work around these days, many Hindus adapt or let the practice fade.
