The numerology of each day

The days of the week are named after planets, and they have been for as long as there have been weeks — Monday is the Moon’s day, Friday is Venus’s, Saturday is Saturn’s. The names survived into English almost intact, and with them a very old idea: that each day has a character, and that some work goes better on some days.

Below is what each day is ruled by, the number it carries, and the kind of work it favours. See also your lucky day, which is calculated from your own number rather than the calendar’s.

Working with the days

Match the task to the day where you can: Mars’s Tuesday for the difficult conversation, Mercury’s Wednesday for writing and negotiating, Saturn’s Saturday for the dull necessary work. Then find your own lucky day, which comes from your Life Path number and may not be any of the obvious ones.

Common questions

Why are the days of the week linked to planets?

Because they are named after them, and have been for as long as there have been weeks. Monday is the Moon’s day, Friday is Venus’s, Saturday is Saturn’s — the names survived into English almost intact.

Does the day of the week really matter?

Treat it as a way of matching a task to a character rather than a rule. Mars’s Tuesday for a difficult conversation, Mercury’s Wednesday for writing and negotiating, Saturn’s Saturday for the dull necessary work.

Is my lucky day the same as my birth day?

Not necessarily. Your lucky day is calculated from your own number rather than from the calendar, and it is often not the day you were born on.
