Bishop Peter Elliot, who is, I suspect ... nobody ever tells me anything ... the man mainly concerned with liturgical questions concerning Ordinariates, may not have given much thought to the question of Local Calendars. This is because he is an Oz and down in Oz the Local Calendars have very few entries.
In England, on the other hand, the Calendars are crowded with Romans and Saxons and medievals and counter-Reformation martyrs; and accordingly they differ quite a lot from diocese to diocese. This week I keep S Edmund Rich (of Abingdon, a few miles to the South) on Tuesday; S Hugh of Lincoln (before the Diocese of Oxford was canonically erected in the reign of Good Queen Mary we were in the great sprawling diocese of Lincoln); and on Saturday, the other S Edmund, the King and Martyr*. But in an Ordinariate ... will people be keeping the Calendar of the Roman Catholic diocese in which they are situate; or will there be a special Ordinariate Calendar? Or both?
In practical terms - and to prevent some poor person from having to do a lot of complicated work at a time which is busy enough anyway - it would probably be neatest (at least temporarily) to put all the observances from all the Local Calendars into a single mainly optional list and leave it to local decision what got observed.
*For the curious: in both the OF and EF masses here I use a calendar extracted from the calendars of the three RC dioceses parts of which are within the Diocese of Oxford; I based it on the canons of Local Relevance which respectively the Sacred Congregation of Rites used to employ for the EF and the Congregation for Divine Worship and etc. etc. operates now for the OF.
Oxford provides an example of why simply imposing the Calendars of a geographical RC diocese would be problematic. The boundary between the RC dioceses of Birmingham and Portsmouth runs through the middle of the Oxford conurbation. South of the Isis one would find oneself using a Calendar which included entries put on it with an eye to the Channnel Isles; North of the river, where the calendar of Birmingham is weighted towards the historical traditions of the far Northern see of Lichfield, one would be cut off from observances relevant to nearby Abingdon ... where my Head Server lives and where Pam and I are just off to do our shopping in the Waitrose.
