Here’s a formula that should work:
IF(
{Date Created},
DATEADD(
{Date Created},
14 + SWITCH(
WEEKDAY({Date Created}),
0, 2,
1, 1,
2, 0,
3, 1,
4, 0,
5, 4,
6, 3
), "days"
)
)
At its core, it’s adding 14 days to the date in {Date Created}
. However, it increases the number 14 by a number that’s based on the weekday of the {Date Created}
value. The SWITCH()
function takes care of calculating the proper number of extra days to add so that the target date always lands on a Tuesday or Thursday. For example, if {Date Created}
is on a Sunday—which will be a 0 when returned from the WEEKDAY()
function—then two more days need to be added to get to Tuesday. (That’s the 0, 2
line in the formula: if a 0 is returned from WEEKDAY()
, add 2 more days). If it’s a Monday (a WEEKDAY()
value of 1), only one day is added, and so on.
