Formula to Generate Which week of the year it is based on date entered in ""Process Date"" Field.

So do you have a field for week that has this formula that tends to pull Week 53-

var number WeeksSinceFirstWeek = 

(ToDays(LastDayOfWeek([date])-[Ending Saturday of First Week of Year]))/7;

$WeeksSinceFirstWeek+1)

Then a [Week number] field with this formula to move week 53 to Week 1?

If([Week number]>52,1,[Week number]

Then just hide the Week field and display Week Number instead?
