Happy Yuletide! 
Merry Yuletide to you! (And a happy new year!)
Template documentationUsage
This template is one of a series of holiday season greetings that can be shared of talk pages of other editors. It automatically places the recipient's name in the salutation and your signature at the end of the message.
Wikipedia is a global community and not all editors celebrate Christmas (or experience the winter solstice in December), so if you are unsure of an editor's preference, please consider using one of the more inclusive options. The {{Not Christmas celebrator}} edit notice can be used to indicate a greeting preference.
