[james28909]: yep, i am scraping a websites date/time stamp from an article. none of that is relevant though because the strings i get are as expected. the returned data from the website is the list of @weekdays
[james28909]: i need to convert those @weekdays to an numerical date based off of scalar localtime
[james28909]: i have thught about this and though about it lol
[james28909]: also remember, that if 'Today' is may 1, then Yesterday is not may 31 lol
