If you are fairly spiritual or religious, you may embark on a period of reflection and meditation during the month of December.
That period beginning with December 1st is important in the awareness of the lives of we who worship the One True God.
Some of us mark the beginning of the Advent season which is that period of preparation, reflection and religious interactions leading up to Christmas.
Other cultures may view it as the start of winter and a time to reflect on the year just past.
The celebration of Advent is seasonal in most Christian denominations as a time of spiritual consciousness and awaiting both the birth and return of Christ at His second coming. It all begins on the 4th Sunday prior to Christmas aka Advent Sunday. It ends on Christmas Eve. It is a time for spiritual reflection.
