my lot update on xmas or boxing day?

Yes/Maybe/No. Give then a break! The FAQs say: "# It is not necessary to post a discussion about your earnings not updating. If your earnings are not up to date, then nobody's earnings are up to date. # If you think there is a real issue concerning your earnings that we have not noticed or it pertains only to you, please contact myLot if your earnings have not updated within a 48 hour period.
