The USCCB Committee on Divine Worship has helpfully published the 2020 Liturgical Calendar for the Dioceses of the United States of America (PDF, free download) on their web site.
The Calendar contains Scripture readings for each observance, details about regional variations in holy days of obligation, and an appendix listing patronal days for Latin American countries and the corresponding celebrations that may be observed when they fall on ferial days.
Also mentioned is the new memorial of Mary, Mother of the Church, which falls on Pentecost Monday; this year that will be June 1, temporarily displacing St. Justin Martyr.
