Day 5

If you don't use the event page to grab the item for that day then you will have to wait for the next day for it to have a systems check on your profile.

You can use the event page to instantly receive the item after meeting the requirements (ie logging in, playing, logging out, then checking on the event page)
To do that, you would need to be logged in on the website afterwards then click on the red "Get" button. The textbox above on the page would say "Sucessful!"
