Excel 中的条件格式比较单元格之间的日期

Question

I have 2 columns that have conditional formatting to compare the Day and Time in the cells.

M compares against K, N compares against L

In both cases, if the cell data is <= then it should return Green. If > then it should return Red.

I have done 45 other data entries and every day and time worked perfectly until the last row. They are the only cells showing Friday. Any ideas why this is happening?

I have an example in the images showing the row just above it where the formatting is working just fine.

Also, the format for the cells is dddd hh:mm.

I did a quick validation formula to see if N46 > L46, produce Y and it does flag as being greater for some reason.

You will need helper columns to retrieve a date from your strings.

You can use this formula - maybe it makes sense to create a LAMBDA function from that (look for according tutorials) - where A3 is the cell with your data (eg Friday 11:30)

=LET(d,A3,
day,TEXTBEFORE(d," "),time,TEXTAFTER(d," "),
weekdays,{"Monday";"Tuesday";"Wednesday";"Thursday";"Friday";"Saturday";"Sunday"},
weekdayIndex, MATCH(day,weekdays,0), (TODAY() + (weekdayIndex-WEEKDAY(TODAY(),2) +1) ) + time)

Then you can use the helper columns for your conditiona formatting.

(I tried: it is not possible to use a LAMBDA function as formula for the conditional formatting).
