Over the years occasional comments on the last outpost of the Christmas season. It’s only every five, six, or eleven years it lands on a Sunday to replace green with white. This year, it’s a mid-week observance. Sit in the purple chair and consider how you might impose your liturgical will on parish and/or school.
Provide candles for Massgoers, or invite them to bring their own?
Special music if such isn’t ordinary during a weekday Mass?
Any edibles and drinks after liturgy?

I can’t speak to school Masses, but for adult daily Mass congregants: why not ask them beforehand to take the temperature of the room, as it were? A lot may depend on what time of day Mass is scheduled and whether daily Mass congregants have a time expectation that would be frustrated by surprise.
And, if something is decided to be special more than usual (were I a daily congregant, I would probably welcome it – but that phase of my life has not yet dawned given COVID despite my recent retirement): communicate it in advance, not just the bulletin of the Sunday before.
