If you happen to be a non Christian pipz, you will ask about Holy Thursday and why we can't have a party or celebration in this day or time. According to Wikipedia, Holy Thursday, Covenant Thursday, Great and Holy Thursday, and Thursday of Mysteries, is the Christian feast or holy day falling on the Thursday before Easter that commemorates the Last Supper of Jesus Christ with the Apostles as described in the Canonical gospels. This day or this week is sacred to us Christians. This is the time we offer prayers, sacrifices in forms of fasting and other abstaining, visit churches and remembering the things that happen to our Lord Jesus Christ when he suffered on the cross and saved us from our sins.
Now, one thing I love about having my birthday falling on Holy Week is no expenses or if there is, it would be less. Hahahah. No party, no celebration equals less expenses, plus peaceful time with my family during these holidays! One way also of abstaining, and serves the purpose of Holy Week.
