seasonal dummy for weekly data s=52

[ch2324]

hi every one
1)for monthly s=12 (@expand(@month)) and quarterly s=4(@expand(@quarter)) it's easy to do the seasonal dummy, but how can do this for weekly data?
2)i have seen that this code generate dummy equal 1 for every first week for each month (data weekly), but how can generate dummy for the second week for each month?

Code: Select all

series first = @date < @datefloor(@date,"month") + 7

when i cahange 7 by 14, it will generate dummy for the 1st and second week for every month, but i need dummy=1 just for second week for every month.
