The billions of Christians around the world will be seen with ashes on their forehead in the form of a cross when they step out of church or religious service.

Ash Wednesday which falls 46 days before Easter, including Sundays marks the beginning of Lent, a period of preparation for the Resurrection of Jesus.

One of these phrases is used, "Remember that you are dust and to dust you shall return" or "Turn away from your sins and believe in the Gospel."
From where do they get the ashes?
The ashes are made from the palms of the previous year's Palm Sunday, they are burned, blessed and then placed on foreheads. And while Ash Wednesday is often associated with Catholics, other churches also recognise it.
Ashes are a way to remind people of their physical and spiritual weaknesses.
