Hello @MehmetMuhanna,

You can perform calculations with dates using the Moment.js library, see code examples in our documentation here.

And to update item in another list, use PnPjs. For instance, update item when the field value has been changed:

fd.field('Field1').$on('change', function(value) {
   pnp.sp.web.lists.getByTitle("ListName").items.getById(1).update({
          Title: value
   });
});

thank you very much @mnikitina but i have the following scenario:
i want to update a field called APPROVED based on a field called ATT_ID on the second list.
can you instruct me how to accomplish this?

@MehmetMuhanna,

What is the ATT_ID field type? Is it a lookup field? Is the value of this field unique?
