That doesn't seem to require a lot of extra work. BTW, I think it was
supposed to be (Day23|Day22) rather than Day23.Day22, but that bit
changes further if we extend to know about leap years.
"LeapYear" expression =>
"(Yr2004|Yr2008|Yr2012|Yr2016|Yr2020|Yr2024|Yr2028|Yr2032)";
### And extend the list whenever you wish to - no particular need to
### calculate
"Last_Saturday" expression =>
"Saturday.((Day31|Day30|Day29|Day28|Day27|Day26|Day25)|(Day24.(April|June|September|November)|(Day23.February)|(Day22.February.!LeapYear)))";
