How Does Polio Travel?

The length of time of day and night varies depending on time of year, and then we can have hours of 40.60 and also 80 minutes. For us it is necessary to know as precisely as possible when making a ritual, so we must arm ourselves with patience, and perform some small calculation. There are also tables that appear to be reliable, but I have not ever tested the effectiveness and I only trust the old calculation, which otherwise retains its charm and gives us the greatest certainty.
To calculate the duration of the hours you need to know what time the sun rises because that will be the first hour of the day and at what time set for the hour that follows will be the first of the night. This and other useful information can be detected by the common lunar year which are on the market such as "Blackbeard." What may seem complex for those who has never done, but with a little practice will become easier then to make things easier we will make a practical example.
Take for example the date 11 May 2008, when the sun rises at 05:44 and sunset at 20.10, then we will have a day length of 14 hours and 26 minutes. These are the hours that marks the clock in the interval between sunrise and sunset, times that by convention are more than 60 minutes, but in our case the minutes will vary, and by convention the hours of day and night will always be 12th 12. Let us return to our calculation.
14 hours and 26 minutes.
translate everything in minutes and have 866 (solar day length in minutes) Divide the length of day
in twelve hours 866:12 = 72.16
We found that each hour consists of 72 minutes and 16 seconds.
May 11 was a Sunday so the first hour, ie one that goes from 5:44 to 6:56 '.16 "was now dominated by the sun. We shall always adding 72' .16" for all others. Remember that after the twelfth hour, he began the first of the night. Attention
this addition can not do it with an ordinary calculator, why do not you ever come back ......
The examples below serve only to demonstrate the difference between how you do the math with the minutes and processes it as a calculator.

05:44 05:44 ................... ...............
00.72.16 00.72.16
---- ----------------------------------
6:56:16 6:16:16 ............... ................
correct calculator Do it by hand adding

hour at a time and will not go wrong.
I know that may not seem easy, but for the success of this important work to be done. As you can see to deal with magic not enough to light a candle and behind a film choreography sometimes there's a great job of preparation. Sometimes!
Good job.
