The book of Numbers, chapter 9, describes a story of a few people who were ritually unclean because they were helping with a funeral.  According to Numbers 19, there is a seven day purification process between contact with a dead body or a grave and entering the Temple.  These men were very disappointed because they were doing a good deed, but because of it they were not able to offer the Passover sacrifice in its proper time.  They went to Moses and asked why should they be left out?  Moses told them, “wait, I will see what the Lord has to say”.

God then told Moses that He had a plan for this already, that if someone misses the first Passover, there is a second chance one month later to offer the Paschal lamb again.

Yesterday was this day, and there is a Jewish custom to eat some of the leftover Matzos (unleavened bread) from Passover yesterday and/or last night.  Some also sing traditional Passover hymns at this meal.  The message is clear, there is always a second chance, so don’t give up!
