`Look people, Catholicism is above all a religion of common sense. The OP tried to go to Mass, was mistaken about the time and had already planned to host a get-together for the Super Bowl so he couldn’t make it to a later one. There is no sin here. Sheesh.

"198. - III. Excuses from assisting at Mass. Any moderately grave reason suffices to excuse one from assistence at Holy Mass, such as considerable hardship or corporal or spiritual harm either to oneself or another.
Therefore, the following are excused: the sick, convalescents, persons who cannot endure the air in church (e.g., certain neurotic persons and sometimes pregnant women in the first or last months of pregnancy); those that have a long way to church, people hindered by the duties of their state (e.g., shepherds, watchmen, policemen on duty, cooks, and those working in mills that may not shut down over Sunday); women or children who would incur the grave displeasure of their husbands or parents by attending Mass; servants whose masters do not permit them to attend Mass (should this happen consistently the servants should seek other employment); those that care for the sick, rescue workers in time of fire or flood; and those who have reason to think that by staying home they can hinder sin; or who would suffer injury to their good name or possessions by going to Church. (Thus: unmarried women who are pregnant, may remain home if by doing so they can avoid disgrace; similarly, those who lack clothing becoming to their social standing; those on a journey; those who would suffer the loss of extraordinary gain by attending Mass). One may miss Mass for the sake of a pleasure trip once or twice if he has no other opportunity during the year, or if it is the last opportunity he will ever have for a certain excursion. (Cf. 60.) Finally, custom in certain localities excuses such as, for example, lying-in women, widows in the first days of their bereavement, engaged persons whose marriage banns are published in the only Mass they can attend."
Can. 1323 The following are not subject to a penalty when they have violated a law or precept:
- a person who has not yet completed the sixteenth year of age;
- a person who without negligence was ignorant that he or she violated a law or precept; inadvertence and error are equivalent to ignorance;
- a person who acted due to physical force or a chance occurrence which the person could not foresee or, if foreseen, avoid;
- a person who acted coerced by grave fear, even if only relatively grave, or due to necessity or grave inconvenience unless the act is intrinsically evil or tends to the harm of souls;
- a person who acted with due moderation against an unjust aggressor for the sake of legitimate self defense or defense of another;
- a person who lacked the use of reason, without prejudice to the prescripts of cann. 1324, §1,n. 2 and 1325;
- **a person who without negligence thought that one of the circumstances mentioned in nn. 4 or 5 was present.

I think it is clear here that we are not expected to kill ourselves to get to Mass. Intent is the key in this situation and this person made an honest effort. Case closed.
