The Full Moon will turn a shade darker when a penumbral eclipse will occur in the 2nd quarter of Rehena constellation in the Zodiacal sign of Taurus (Vrushabha) beginning 13.03 hours (local time) on Monday, November 30, 2020.

This eclipse lasting four hours and 21 minutes which precedes the Annular Solar Eclipse that will occur on December 14, 2020, will not be visible in Sri Lanka for it will be below the horizon. It will be visible in North and South America, Australia and parts of Asia as a darker Full Moon during the maximum phase of the eclipse.  
The greatest eclipse will occur at 15.12 hours on November 30. It will end at 17. 24 hours on 
November 30.

An eclipse never comes alone, because a Solar eclipse always occurs about two weeks before or after a Lunar eclipse.  

According to the ancient Indian Rishis it is inauspicious to start any important event in life or embark on any plan or program for that matter on the day of a Solar or Lunar eclipse and during the three days both preceding and following the day of the eclipse counting a total of seven days.

It is also the general opinion of the savants of Astrology that it is  inauspicious to commence any important event or plan during the running of either the Zodiacal sign or the constellation in which the eclipse occurs either on the day of the eclipse or within the seven days preceding or the following the day of the eclipse which add up to 15 days.
