Tintilaro is the usual Esperanto version. Not specifically a Christmas (indeed, in Oz this would be more appropriate in July); fairly close translation of Pierpont's first two stanzas and the chorus.

Zamenhof's Birthday is this coming Sunday (Seattle Esperanto Society meeting at 1 pm for lunch at The Old Spaghetti Factory); the good Doctor will be 143, and I'm sure we'll sing the hilarious "zambankanzono" (approx. = "Zamenhof's birthday carol") Feliĉegan Naskiĝtagon to the "Jingle Bells" tune.
