The three day lent is a lent of attrition and repentance commemorating
the repentance of the people Nineveh at the preaching of Prophet Jonah.
This lent starts three weeks before the start of the Great Lent.
The Great Lent starts by commemorating the first miracle performed by Jesus i.e.
turning water into wine at the wedding feast at Cana of Galilee. The Gospel reading
for each Sunday of the Great Lent is about a miracle performed by Jesus.
