How can I filter list (present in my database) with respect to an input? For eg, I have a list of birthdays, and I want to get those birthdays from that list which has occurred in the past week/past month.
Depends on how you want it setup, but you could use 2 Date inputs (date/time picker elements), and then to find birthdays between those dates use something like this:
Do a Search for Birthdays
Date > Input Date Start
Date < Input Date End
This only works for specific Birth Dates, it will be a little different if you want birthday, as you will need to normalize the Year value (change all the Year values to the same)
