Rounding to the following Sunday

[SPOATO]

Racking my brain to get the following to work: =IFERROR(IF(D5=0,"",D5+45),IF(D5="","",D5+7-MOD(D5-1,7)))

D5 being the source date that I'm adding 45 days to and then rounding to the following Sunday. Honestly wouldn't mind figuring out the previous Sunday as well. We are trying to set ordering dates to Sunday to help with Monday through Friday scheduling. I've been using Numbers iOS/Mac for the past 2-3 years so my Excel is very rusty. Any help is GREATLY appreciated.

Spoato, assuming that the date is in cell [D5] try this:

=D5-WEEKDAY(D5) - truncated to the previous Sunday

=D5+7-WEEKDAY(D5) - rounded to the next Sunday

Thx,geo77

As a single statement it works perfectly. I keep getting errors when changing the second statement from current formula. I need both to run in order, but as shown will only process the first statement.

Side note, digging your work on the link.
