Just as one may pray whenever one likes, praying on particular days and nights can also be very effective.

The eves and nights of all Eids
The month of Ramadan
Odd numbered nights after the 20th of Ramadan (eg. 21st, 23rd, etc.)
The nights of Eid al-Fitr and Eid al-Adha
The 10th day and night of the month of Muharram
The 10th day of the month of Zilhijja
It is important to note that it is more optimal to pray during the night hours, particularly in the hours after midnight.
Two points are crucially important in regards to the time of prayer:
- One’s inner state
- External conditions
One’s inner state is the spiritual state and general condition at the time of prayer. For it is important to pray with much fervor and passion because only then does the person engage in high levels of concentration, which enables the brain force to become dense and directed towards one particular vector.
External conditions pertain completely to the state of the external environment at the time of prayer. Little or no sunlight is ideal as the cosmic rays emitted by the Sun generally impede brain waves.
Additionally, conditions for prayer are more optimal during the hours of Jupiter and Venus, when softer and more nourishing rays are emitted, rather than say the hour of Mars, when the rays may be harsher.
When events may lead to disputes and quarrels and sub-optimal results during other hours, you will be surprised at how smoothly things flow during the hours of Venus or Jupiter, and how complex issues are easily resolved.
Information on how to calculate these hours may be found via various publications and software applications.
