There is no such rule. As stated, it would by praiseworthy to try and attend a weekday Mass, it does not fulfill or replace our Sunday obligation.If we are unable to attend on Sunday due to reasonable circumstances, we should attend on the weekday of the same week. So, it is more than relevant.
From the Catechism
The Sunday obligation
2180 The precept of the Church specifies the law of the Lord more precisely: "On Sundays and other holy days of obligation the faithful are bound to participate in the Mass."117 "The precept of participating in the Mass is satisfied by assistance at a Mass which is celebrated anywhere in a Catholic rite either on the holy day or on the evening of the preceding day."118
2181 The Sunday Eucharist is the foundation and confirmation of all Christian practice. For this reason the faithful are obliged to participate in the Eucharist on days of obligation, **unless excused for a serious reason (for example, illness, the care of infants) or dispensed by their own pastor.**119 Those who deliberately fail in this obligation commit a grave sin.
2182 Participation in the communal celebration of the Sunday Eucharist is a testimony of belonging and of being faithful to Christ and to his Church. The faithful give witness by this to their communion in faith and charity. Together they testify to God’s holiness and their hope of salvation. They strengthen one another under the guidance of the Holy Spirit.
vatican.va/archive/ccc_css/archive/catechism/p3s2c1a3.htm2183 "If because of lack of a sacred minister or for other grave cause participation in the celebration of the Eucharist is impossible, it is specially recommended that the faithful take part in the Liturgy of the Word if it is celebrated in the parish church or in another sacred place according to the prescriptions of the diocesan bishop,** or engage in prayer for an appropriate amount of time personally or in a family **or, as occasion offers, in groups of families."120
And from canon law
vatican.va/archive/ENG1104/_P4N.HTM§2. If participation in the eucharistic celebration becomes impossible because of the absence of a sacred minister or for another grave cause, it is strongly recommended that the faithful take part in a liturgy of the word if such a liturgy is celebrated in a parish church or other sacred place according to the prescripts of the diocesan bishop or that they devote themselves to prayer for a suitable time alone, as a family, or, as the occasion permits, in groups of families.
As you see from the texts, there is nothing about going to a weekday Mass. There are suggestions on keeping the Lord’s day sacred, “devote themselves to prayer.”
