I found that the Dustbin Day does not move forward to the following
Friday on Easter Monday. I checked back a couple of years and it it
seems to always be the case.

It occured to me that the Easter OMIT lines were the issue, and putting
the two lines above _after_ the Easter OMIT lines solved the issue.

I thought that the lines were not order sensitive. Is this a special
Easter thing?
