Blessing incense on Epiphany

In Paul Turner's Blog by Paul Turner

Q: Dear father Turner,I have a question for you. I would like to have incense blessed by a priest I know, using the old Roman ritual blessing and it says that it should be done on the Epiphany. Question – can that same blessing be used in any other day besides the feast of the Epiphany?

Thank you and have a happy Christmas Octive.

A: The blessing in the ritual, as you see, says “on Epiphany.” I don’t know if there’s a provision for using it on some other day. I believe it should be effective on other days, but I don’t know how to show the permission.
