AppleScript: < and > a set date

As red_ mentioned, you need to convert the text from the page to a date object in order to do any comparisons.

This is a lot trickier than it should be, but here's a revised version of your script that should do the trick.

It uses Apple's NSDataDetectors to extract the date from the string - this should be reliable for various date formats:

use framework "Foundation"

use scripting additions

tell application "Google Chrome"

repeat with x from 0 to ((execute active tab of first window javascript "document.getElementsByTagName('p').length") - 1)

set theEnd to execute active tab of first window javascript "document.getElementsByTagName('p')[" & x & "].outerHTML"

if theEnd contains "issue-date" then exit repeat

end repeat

set theEnd to execute active tab of first window javascript "document.getElementsByTagName('p')[" & x & "].innerHTML"

set e to my strToDate(theEnd)

set issueDate to (date "Thursday, March 1, 2018 at 12:00:00 AM")

if e is greater than or equal to issueDate then set theResult to "Current"

if e is less than issueDate then set theResult to "Ended"

return theResult

end tell

on strToDate(thisString) --

tell current application

set m to its ((NSDataDetector'sdataDetectorWithTypes:(its NSTextCheckingTypeDate) |error|:(missing value))'s matchesInString:thisStringoptions: 0range:{0, length of thisString})

if (count m) > 0 then

set d to (item 1 of m)'s |date|() -- get the NSDate of the first item

return d as date

end if

end tell

return "" -- no match in this string

end strToDate
