Timing
As to the proper time to divine, opinions differ. One line of thought says night is better than day for divination, because the energies are calmer, more inwardly-focused and more other-worldly at night. Then again, ancient Egyptian priests and priestesses preferred to practice lamp divination at midday in a completely dark room. Another divination source says never do a reading when the weather is stormy or windy outside, because then the energies will be too unsettled to do a proper reading.
One dice divination expert says dice divination should be performed on a Monday or a Wednesday. Another says it can be performed on Mondays, Tuesdays, Wednesdays, and Thursdays, but not attempted on Fridays and Saturdays. (No opinion was volunteered about Sundays). Madame Le Normand, diviner to the Emperor Napoleon Bonaparte and his first wife, Empress Josephine, reportedly flat-out told her clients that if they wanted a positive response to their questions, then Friday was the proper time to consult her.
Some methods of divination are not time-dependent and may be performed at any time, because the timing will not affect the result at all. Examples of this are number divination, name divination, calendar divination, and lexigram divination.
The key factor to consider in deciding when to divine is this: calmness. The best time to divine is when the diviner is feeling calm and secure, and when the environment is calm and secure. You can take the weather outside into account if you wish, but the most important weather is inside you. If you can establish an oasis of calm inside yourself, even in stormy emotional times, you can divine anytime.
Another timing factor you may want to consider is regular habit. If you establish a set time of the week or day of the month for the practice of divination, then you may be able to establish in all levels of your mind the message “Now is the time for divination. Set aside all my other concerns and worries at this time, and give me true answers.”
