Today is the Feast of the Presentation of Our Lord Jesus Christ in The Temple (Candlemas). Traditionally, candles are blessed on this day.
Here's a Robert Herrick poem for the day:
THE CEREMONIES FOR CANDLEMAS DAY
Kindle the Christmas brand, and then
Till sunset let it burn;
Which quench'd, then lay it up again,
Till Christmas next return.
Part must be kept, wherewith to teend
The Christmas log next year;
And where 'tis safely kept, the fiend
Can do no mischief there.
In some traditions it's fine to keep Christmas decorations up until Candlemas. I did that one year and enjoyed it very much!
