API Management: Get the difference between two dates

Products

• CA API Gateway

Issue/Introduction

We would like to know how can we get the difference(no. of days) between two dates. For example, the input dates will come in query parameters to the Gateway:

&date1=12-11-2019&date2=12-30-2019 

Environment

All supported versions of the API Gateway

Resolution

A sample policy is attached that makes use of the Execute JavaScript Assertion
