Need to open up a date parameter

I need to temporarily modify a date parameter in a REST Get snap. The parameter ‘date_added’ uses the previous date:

date_added = Date.parse(

I need to change it to include the range August 1st to previous date. So, I’m thinking of something like this: 2021-08-01 - Date.parse(
Can someone offer some examples on how I would code this? I’m not very familiar with the language in SnapLogic.


Hi @vcocco,

If you think of getting the days between those dates, then you need to just switch the places of the dates.
Math.floor(( - Date.parse("2021-08-01") / (1000*60*60*24))

But if you want to get range of dates then, use this expression.
sl.range(0, Math.floor(( - Date.parse("2021-08-01") / (1000*60*60*24))).map(x => Date.parse("2021-08-01").plusDays(x))

This will return you array with range of dates, so after the mapper you can use JSON Splitter snap to split the dates in more documents.

I am attaching simple pipeline, containing another solution(which will generate dates from given starting point to a previous day(calculated from today’s date)) using Sequence Snap:
