The Muslim's Position on the End of the Year and the Ruling on Designating It for Specific Acts of Worship

Question:
May Allah reward you. This questioner says: Shaykh Salih (may Allah preserve you), in a few days we will bid farewell to a year and welcome a new year of our lives. What is the lesson in the succession of months and the completion of these years and the welcoming of new years? And what is obligatory upon the Muslim?

Answer:
Every day we bid farewell to a year and welcome a new one, specifically at the end of the twelfth month. This is a calculation by which terms are known; by it, the terms of transactions and correspondence are known. It is a conventional matter. It is a conventional matter.
'Umar ibn al-Khattab (may Allah be pleased with him) established it during his caliphate when documents would come to him without dates, so he established this date and began it with the month of Muharram because it is the month in which the pilgrims arrive after their Hajj. It is a conventional matter and is not designated for anything.
It is not designated for fasting, nor for standing in night prayer, nor for anything other than the rest of the days of the year. Yes.
