There is not universal agreement as you can see by reading the commentary by Edward Peters, JD, JCD, Ref. Sig. Ap.
“But what qualifies as a ‘universal’ response in canon law goes considerably beyond what English-speaking North America might hold (even if it is held for very good reasons). Consider these overseas canonical commentaries, three of which hold for a noon start-time and one of which holds for a 2:00 pm start time”

There was a series of changes applied when the 1917 canon law was in effect.
On Epiphany, 1953, Pope Pius XII issued “CHRISTUS DOMINUS – Concerning The Discipline To Be Observed With Respect To The Eucharistic Fast.”
This allowed evening Masses for the first time and set 4 p.m. as the earliest an ‘evening’ Mass could be celebrated:
Rule VI. If the circumstance calls for it as necessary, We grant to the local Ordinaries the right to permit the celebration of Mass in the evening, as we said, but in such wise that the Mass shall not begin before four o’clock in the afternoon.
Then Eucharisticum Mysterium (Instruction on the Worship of the Eucharistic Mystery) May 25, 1967:
- Anticipating the Sunday and Feast Day Masses on the Previous Evening
Where permission has been granted by the Apostolic See to fulfill the Sunday obligation on the preceding Saturday evening, pastors should explain the meaning of this permission carefully to the faithful and should ensure that the significance of Sunday is not thereby obscured. The purpose of this concession is in fact to enable the Christians of today to celebrate more easily the day of the resurrection of the Lord.
All concessions and contrary customs notwithstanding, when celebrated on Saturday this Mass may be celebrated only in the evening, at times determined by the local Ordinary.
In these cases the Mass celebrated is that assigned in the calendar to Sunday, the homily and the prayer of the faithful are not to be omitted.
What has been said above is equally valid for the Mass on holy days of obligation which for the same reason has been transferred to the preceding evening.

1917 canon law
Can 821 §1. Missae celebrandae initium ne fiat citius quam una hora ante auroram vel serius quam una hora post meridiem.
§2. In nocte Nativitatis Domini inchoari media nocte potest sola Missa conventualis vel paroecialis, non autem alia sine apostolico indulto.
§3. In omnibus tamen religiosis seu piis domibus oratorium habentibus cum facultate sanctissimam Eucharistiam habitualiter asservandi, nocte Nativitatis Domini, unus sacerdos tres rituales Missas vel, servatis servandis, unam tantum quae adstantibus omnibus ad praecepti quoque satisfactionem valeat, celebrare potest et sacram communionem petentibus ministrare.
Can 1247 §1. Dies festi sub praecepto in universa Ecclesia sunt tantum: Omnes et singuli dies dominici, festa Nativitatis, Circumcisionis, Epiphaniae, Ascensionis et sanctissimi Corporis Christi, Immaculatae Conceptionis et Assumptionis Almae Genitricis Dei Mariae, sancti Ioseph eius sponsi, Beatorum Petri et Pauli Apostolorum, Omnium denique Sanctorum.
§2. Ecclesiastico praecepto dies festi Patronorum non subiacent; locorum autem Ordinarii possunt sollemnitatem exteriorem transferre ad dominicam proxime sequentem.
§3. Sicubi aliquod festum ex enumeratis legitime sit abolitum vel translatum, nihil inconsulta Sede Apostolica innovetur.
1983 canon law
Can. 1248 - §1. Praecepto de Missa participanda satisfacit qui Missae assistit ubicumque celebratur ritu catholico vel ipso die festo vel vespere diei praecedentis.
The 1983 canon law does not specify evening at a particular hour. The word used is vespere. The antynoym for vespere (in the evening) is matene (in the morning).
Per the Exegetical Commentary (Spanish) of 2004, the intention of the 1983 canon law was to not make the time precise. Noted in Communicationes 15, pp. 251-253."
"the “Exegetical Commentary” remarks about those who wrote the canon that the wording is “intentionally ‘general in order to avoid casuist situations and anxieties.’”
