Translation:Christmas is a good time for your health.
Apparently spring and summer are worse. http://en.wikipedia.org/wiki/Seasonal_effects_on_suicide_rates
Thank you for your comment Timothy, I learned a bit more Roman Catholic vocabulary today! :) While I agree with your suggestion, Duo has asked me to treat 'Weihnachten' as both a plural noun and singular noun at different times. So how do I know which one to use, say, if I want to ask someone at what time the Christmas market begins in Switzerland? (Which I will!)
why should xmas be a good time for your health? WHAT A RIDICULOUS ASSUMPTION. xmas is a time of stress, for those that celebrate it, going out into crowds, buying crap for people you do not care for, going into debt, spending unneeded amounts of money, eating fatty unhealthy foods and drinks? BS!
X has been a shortening of Christ (Gr. Χριστός) since at least the second century, and Xmas is attested since 1755. There are older shortenings involving X such as X'temmas, dating from 1551 and others from Old English even. Personally, however, I don't use shortenings very often but this one is in the dictionary.
