On the day the Holiday Party was released, I tried changing my computer’s date to see if I could get all of the items early. However, it didn’t work for me, yet it worked for others. I was rather confused. However, I found out what I was doing wrong. If you’re interested in getting all the items ahead of time, then keep on reading.
I did it by first logging onto Club Penguin – do NOT change your computer’s clock date yet. I then went to the Forest, then changed the date on my computer to December 25th – make sure the time is past midnight PST. I then went to the Snow Forts to verify I did it correctly. If the day on the clock tower says it’s Sunday, you did it right. If not, you need to try again. If it’s not Sunday (or a day that isn’t the day it really is in real life) it’s not right. If it’s the day you changed it, to, it worked correctly. Simply go back to the Forest and then get the items. Just be sure to change your computer date back afterwards!
