Traditionally, in Chaldean numerology, this is an unlucky number, governing inner struggles and opponents, unstable success, and rapid changes, and it is considered unpredictable and unfavorable. It is composed of two sevens, and the vibrational key of this number is 5 (7 + 7 = 14; 1 + 4 = 5). Modern Chaldean numerologists often tend to forget that the number 7 is primarily a lunar number, with 7 representing half of the lunar cycle and the number 2 the other half.

Thus, 7 undoubtedly rules change, and the number 5 is also changeable. For this reason, it is very similar to the number 14 and must change its affairs every five years, or even sooner, and be wary of illusions. Periods of great stress are likely; the number may also bring psychological pressure, and there is also a possibility that this number influences a weaker immune system. The reason for all this lies in the many changes, many of which may be unexpected.

In more contemporary approaches, the number is often described in a more favorable light, somewhere between the meanings of the numbers 14 and 23. This raises the question of where modern numerologists obtained the idea that this is a lucky number. I do agree, however, that it is said to confer quite a few talents. With this number, caution is certainly recommended.
