How are you defining the weekly return?

It is the change that happens in the level of index (price) from Wednesday to Wednesday and I will use to calculate it using
log(price t/price t-1).

Create a weekly page that starts on a Wednesday. Then copy the daily data over to the weekly page, using a match last frequency conversion method. Then do the calculation on the weekly data.
