Right but it seems like we have some inconsistencies on this. When they mention the tax deadline to be midnight of April 15th, they generally mean you have all of April 15th to file it. What they actually mean is 11:59pm because technically midnight becomes April 16th. When I worked for airline scheduling, they specifically avoided showing 12:00 am because that tended to confuse passengers. Just thought I’d mention this.
Another convention which is unfortunately (because it is so useful) not universal is to use 0000 to denote the midnight at the beginning of the day (eg 0000 Monday) and 2400 to denote midnight at the end of the day (2400 Sunday is the same instant as 0000 Monday). Just another thought to mention.
Then there was the debate over whether 2000 or 2001 was the start of the new millennium…Another convention which is unfortunately (because it is so useful) not universal is to use 0000 to denote the midnight at the beginning of the day (eg 0000 Monday) and 2400 to denote midnight at the end of the day (2400 Sunday is the same instant as 0000 Monday).

So have you read about UTC leap second? for UTC, 00:00:00 begins a day.Another convention which is unfortunately (because it is so useful) not universal is to use 0000 to denote the midnight at the beginning of the day (eg 0000 Monday) and 2400 to denote midnight at the end of the day (2400 Sunday is the same instant as 0000 Monday).

There is only a vigil Mass for Monday if Monday is a Holy Day of Obligation which hasn’t been abrogated. For instance, if December 24 is a Sunday, then a Sunday evening mass would be the Christmas Vigil Mass. (And since Christmas “midnight mass” is a misnomer in most places–every parish around me, and near my family in another state, has “midnight mass” at 9:30 or 10:00 pm, the Sunday evening is a true vigil for Monday.) Oh, you cannot get double credit for attending Sunday evening Mass if it’s a vigil for a Monday holy day. The OP’s parish would not have the Sunday evening for Sunday obligation Mass that particular week.
The Mass setting might be the vigil for the next day, but that does not mean you cannot fulfill your obligation to assist at Mass for Sunday at that Mass.
Actually, nowhere in the Canon or the Catechism does it say that one can fulfill both the Sunday obligation and the Holy Day obligation by attending one Mass. You attend the Christmas Vigil, you are fulfilling the holy day obligation and that is it.The Mass setting might be the vigil for the next day, but that does not mean you cannot fulfill your obligation to assist at Mass for Sunday at that Mass.
The readings, prayers, hymns, et cetera do not matter wrt to fulfilling the obligation to assist at Mass on Sunday. :nope:
Only the timing matters (presuming we are speaking about a Mass in a Catholic rite). :yup: Does it fall between the preceding evening and the midnight that ends Sunday? :yup: If yes, then you can fulfill the obligation to assist at Mass on Sunday at that Mass.

Not A Canon Lawyer, But A Liturgical Calendar Nerd
If the Christmas Vigil Mass is celebrated on a Sunday it satisfies either the Sunday Mass or the Christmas Mass obligation.
While this is the correct rationale underlying the discipline, it is important to clarify (as tee_eff_em has) that when we are asking about fulfilling the *obligation *the liturgical day is irrelevant - the calendar and clock timing determine the window for fulfillment. Typically if a solemnity falls on Saturday that evening is NOT the liturgical day of Sunday. Likewise there are some Sundays evenings when, because of a Monday solemnity, the liturgical day has already changed over to the following feast. (It’s even possible, with local solemnities, for liturgical Sunday to last only from 00:00 Sun. to late afternoon, ca. 16:00, because it is bracketed by higher-ranking liturgical days). In neither case does one lose the ability to fulfill the obligation at any point from Sat. eve to Sun. 11:59pm.
So if they don’t remove the Holy Day obligation to attend on Monday or Saturday, that means you have to attend twice during that two-day period?
In the USA for the Latin Church, both Christmas and Immaculate Conception when occurring on Saturday or Monday, are obligatory in addition to Sunday. But then there is the evening extension so it is more than 48 hours available for the two obligations.
Yes.
For the Latin church sui iuris the liturgical day is midnight to midnight, however the* celebration of the solemnity* begins on the prior liturgical day and may end earlier on the solemnity. This is consistent with the Latin liturgical norms and canon law.
Yes.
The midnight to midnight approach also avoids the problem of having overlapping solemnities. Just sayin…
However, the liturgical day of Solemnities is not from midnight to midnight. That approach is contrary to the Church’s liturgical laws. Solemnities begin in the evening at the time of First Vespers.
