Is it possible to change the date of Christmas in Alexa?

[Ktmfan]

We will be celebrating Christmas on December 30th this year, due to me being away on Xmas day.

My kids ask Alexa “how many days until Christmas”

Is it possible for me to set December 30th as “Christmas day”? 

If not, I’m going to have to unplug Alexa until after Christmas.

even if using blueprints, alexa will still give the actual number of days to christmas.   You will have to use a different name for your holiday.
