Ever have one of those days when everything goes right for you? When you make that presentation, or interview for that job and you can do no wrong; everything just clicks. Numerology can predict those days for you, those days when the universe is on your side. We call those days 'Personal days'.
Calculating your Personal Days
To determine if a particular day is a Personal Day for you, we need to calculate the Universal Day number for a particular day and then compare it to your Life path number. The Universal day number is calculated by adding all the digits of the Gregorian date together via faddic addition to get a single digit.
For example, Valentines day 2007 is a Universal day (7). The calculation is:
2 + 14 + 2007 = 2023 = 2 + 0 + 2 + 3 = 7.
Your Life Path is calculated by adding all the digits of your date of birth with faddic addition:
(For example Johnny Depp, born June 9th, 1963 ; 6 + 9 + 1963 = 1978 = 1978 = 25 = 7)
When the Universal day number equals your Life Path number, then the day is a 'Personal Day' for you; the universe is literally in step with you that day. So, Johnny Depp had a 'Personal Day' on Valentines day this year.
Biorhythms and Bad Days
In a similar vein, you can have days when the universe works against you. Biorhythms predict that certain days can be bad for you. On these days, you will tend to be more accident prone and need to take extra care to avoid mis-haps. To my mind, one of the more interesting situations where these were used was when the Ohmi Railway company in Japan, used Biorhythims to predict bad days for their Bus drivers in the 1970's.
They would produce a card, and notify drivers when they were scheduled to have a bad day ahead of time. They claimed to have a 50% drop in accident rates for their busses when they implemented this.
Conclusion
By knowing your Life Path number, and calculating the Universal Day, you can know ahead of time when to plan your critical meetings, to get the universe working with you. Perhaps part of the effect is a placebo, caused by our knowing ahead of time that today is our lucky day, but even so, if it works you should use it. As for me, I never start a really important job in my life except on a 'Personal day'.
