Tcsh variable problems

Tcsh variable-Linux general technology-Linux technology and application information. For more information, see the following section. Set weekDay = "'date + % '"
If ("$ weekDay" = "golden week") then
Set d1 = "'date-d + 2day + % d '"
At 00:05 + 2 days <EOF
/Ln/NKS_BAT/send_newswave.tcsh>/Ln/NKS_LOG/send_newswave $ d1.log
EOF
# What is the sunrise time of tuji? R: why -----------------------------------
Else
Set d1 = "'date-d + day + % d '"
At 00:05 + 1 days <EOF
/Ln/NKS_BAT/send_newswave.tcsh>/Ln/NKS_LOG/send_newswave $ d1.log
EOF
Endif
The above code is executed normally
However, if the following code is added
Set nen = "'date-d-1day + % Y '"
Set tsuki = "'date-d-1day + % B '"
Set hi = "'date-d-1day + % d '"
Set kyou = "$ hi $ tsuki $ nen"

It is not normal. The problem is that there are no hi, tsuki, and nen variables, but we can see that I have defined them. I don't know what the reason is. I want to instruct everyone, thank you very much.
