The collects at morning and evening prayer are pretty straightforward on an ordinary feria, but I have questions about feast days. 1. On a holy day, do you say both the collect for the Sunday and the collect for the feast? 2. Is it different if the holy day falls on a Sunday versus if it falls on a weekday? 3. If you do say both, is there a particular order to say them in? 4. Would anything about the above be different for BCP holy days versus the ones from Lesser Feasts and Fasts? 5. I have heard that there must be an odd number of collects, but I don't see anything stating that in my 1928 BCP. Is that actually a rule?
