Adjusting "Tomorrow's" date if tomorrow is a holiday

I have a dataset we can call 'jobs' which has one row for each job on our calendar.  Row has a column that says if the job is occuring on a holiday or not.  I want to filter on the individual card levels based on if there is a holiday tomorrow, 2 days from now, 3 days from now, etc.

 

Job #    |     JobDate     |      Holiday

1           |      9/3/18         |      True

2           |      2/1/18         |      False

3           |      5/4/18         |      False

 

I am using this code as a filter on many cards to show "Tomorrow's jobs" or Sat-Mon in the case of Friday.  However, I need to adjust this so that if tomorrow is a holiday to show both tomorrow and the next day.  If the holiday happens on Monday and today is Friday I need to show all jobs from Sat-Tues.

 

-- When 'True', show tomorrow's jobs except on Fridays display upcoming Sat-Mon jobs, on Saturday's display upcoming Sun-Mon jobs.

case 

when
	(DAYOFWEEK(CURRENT_DATE())=1)
	and (DATE(`JobDate`) = DATE(ADDDATE(CURRENT_DATE(), INTERVAL 1 DAY)))
    then 'True'
    -- On Sun show Mon

when
	(DAYOFWEEK(CURRENT_DATE())=2)
	and (DATE(`JobDate`) = DATE(ADDDATE(CURRENT_DATE(), INTERVAL 1 DAY)))
    then 'True'
    -- On Mon show Tue

when
	(DAYOFWEEK(CURRENT_DATE())=3)
	and (DATE(`JobDate`) = DATE(ADDDATE(CURRENT_DATE(), INTERVAL 1 DAY)))
    then 'True'
    -- on Tue show Wed

when
	(DAYOFWEEK(CURRENT_DATE())=4)
    and (DATE(`JobDate`) = DATE(ADDDATE(CURRENT_DATE(), INTERVAL 1 DAY)))
    then 'True'
    -- On Wed show Thur

when
	(DAYOFWEEK(CURRENT_DATE())=5)
    and (DATE(`JobDate`) = DATE(ADDDATE(CURRENT_DATE(), INTERVAL 1 DAY)))
    then 'True'
    -- On Thur show Fri

when
	(DAYOFWEEK(CURRENT_DATE())=6)
    -- Change to 4 when holidays on Monday. 3 When Normal week.
    and (DATE(`JobDate`) <= DATE(ADDDATE(CURRENT_DATE(), INTERVAL 3 DAY)))
    and (DATE(`JobDate`) > DATE(ADDDATE(CURRENT_DATE(), INTERVAL 0 DAY)))
    then 'True'
 	-- on Fri show upcoming sat, sun, mon

when
	(DAYOFWEEK(CURRENT_DATE())=7)
    and (DATE(`JobDate`) <= DATE(ADDDATE(CURRENT_DATE(), INTERVAL 2 DAY)))
    and (DATE(`JobDate`) > DATE(ADDDATE(CURRENT_DATE(), INTERVAL 0 DAY)))
    then 'True'
    -- on Sat show upcoming sun, mon

else 'False' end

Thank you in advance for the help!

    Hello!

    You will need to use the LEAD () OVER() or LAG () OVER() beastmode functions to accomplish this. Because we need each comparison to happen on the same row. These two functions will allow us to do this. 

    For example

    CASE

    WHEN `Holiday` = 'True' THEN 'Holiday Today'
    WHEN LEAD (`Holiday`,1,0) OVER( ORDER BY `date`) = 'True'  THEN 'Holiday Tomorrow'
    WHEN LEAD (`Holiday`,2,0) OVER( ORDER BY `date`) = 'True'  THEN 'Holiday In 2 Days'

    WHEN LEAD (`Holiday`,3,0) OVER( ORDER BY `date`) = 'True'  THEN 'Holiday In 3 Days'
    ELSE 'No Holiday in the Next 3 Days'
    END

    (I always make the mistake of forgetting to add a space between LEAD and ()) 
    Cheers!
