Recently, I have to output the age of a date in words and didn't have a framework to work with. The first steps were to parse the given date into an array and create a timestamp with the individual parts. The difference between the timestamp of now and the created timestamp yielded the age in seconds. The result can be used to compare with seconds of a day, week, etc.

The code snippet in the post outputs the difference between two timestamps (then and now) it a bit more friendly way (ex. 4 months, 2 weeks, 2 days).

This function is production ready and you can use it in any of your application which mainly works with these date difference. I have found it somewhere in web, just forgot the source. Thanks to the unknown author of this excellent function.

The rest of the post is the function itself that takes in the interval string (formatting), the start date, end date and whether to use timestamps or not.
