On Obtaining Two Separate Plenary Indulgences for New Year's Eve and New Year's Day?

The following information comes from *the Manual of Indulgences: Norms and Grants translated into English from the 4th edition (1999) of Enchiridion Indulgentiarum: Normae et Concessiones)* which I think is the most up to date edition. In addition to being a baptized person in the state of grace and performing these two pious acts with the intentions of gaining the plenary indulgences (one for the Day of New Years and the other for the day before)---as only one plenary indulgence can be gained in any one day for oneself, there are the other usual conditions: (1) sacramental confession, (2) Holy Communion, and (3) praying for the Pope's intentions, all within a few weeks of the act, and (4) with complete detachment from all sin, even venial. It would appear from the wording used (e.g., "assist"), that these prayers must be recited publicly (other sources of information also would confirm this). QUESTION: In order to possibly obtain both of these plenary indulgences which, the acts of which are done on separate days (such as before midnight and after midnight), are two sets of prayers for the intentions of the Pope, two separate sacramental confessions, and two receptions of Holy Communion required? Thank you.
