The Day and Month Number can be calculated in several ways. One method is to add together all the digits in the day and the month (for example, for November 13: 1 + 3 + 1 + 1 = 6). Another method is to add the numerical values of the day and the month (for example, 13 + 11 = 24; 2 + 4 = 6). A third method is to derive a “bridge number” from the essence of the day and the month (for example, 1 + 3 = 4 and 1 + 1 = 2, giving a bridge number of 42; 4 + 2 = 6).

Most Chaldean numerologists do not take the Day and Month Number into account in their analysis. However, its significance is emphasized by Chaldean numerologist Heather Alicia Lagan. She refers to this number as the “Life Path”, even though this term is usually used for the number that combines the day, month, and year of birth. Chaldean numerologists of the 20th century didn’t use this number. Instead, Cheiro used his own model of combining the influences of the month and the day by adding the zodiac number to the day number. Based on my findings, this approach is weaker than using the actual digits that make up the day and month.

The Day and Month Number certainly does not carry as much weight as the day of the month or the Life Path number. In short, it represents our relationships and the emotions connected to them, and to some extent, our goals.
