15 August, the Feast/Solemnity of the Assumption of the Blessed Virgin Mary, is a Holy Day of Obligation on the Latin Church’s universal calendar and in calendars of particular countries (cf. can. 1246). It isn’t transferred.
So, I remind the readership that you are obliged to hear Mass on Thursday, 15 August.
Make a plan.
As a matter of fact, if you are able, make a plan to fulfill your obligation by participating at Holy Mass in the Extraordinary Form!
Also, please remember that there is a special blessing of herbs in the traditional Rituale Romanum. Remind Father to bless the herbs you bring before Mass begins.
I invite you to post below opportunities for the Usus Antiquior in your area. (Please don’t send them by email to me to post for you – register and post them yourselves!)
That said, …
In Madison, WI: TLM at the Bishop O’Conner Center at NOON.
