I will try and order the book, hopefully it will help me. By any chance do you know how one celebrates these feast outside of the church (in one's home)?
One normally lets the feast or commemoration come and go without ever realizing it
If you mean how could one, there ara number of options.
When praying Compline, some people will insert the doxologies, after "Hail to you!" and before "We exalt you...", just as would be done in the Raising of Incense. Start with "Shere ti Parthenos...", continue with the doxology for the virgin, then the doxology for the saint of the day, then the doxology or a verse for the patron of your church, then "be our advocate...". I don't know whether this is right or wrong, but some people, including some priests, do this. This would only add a few minutes to the evening prayer. This is fairly easy to do, as long as you know the 5 (or 6) tunes for the seasons. If you have trouble starting them, you can just have a recording of the first verse to play to get you started, then continue. It's easiest to memorize the first verse in English of the doxology of one occasion in each tune, and sing that in your head for a second so you can start "Shere ti Parthenos" in that tune.
Some people will say a Veneration at home, usually after they pray Compline. At minimum this would consist of singing "Khen ef Ran", then Axia for the Virgin, then Axios or Axia for the saint of the day, finally Axios or Axia for the patron of your Church. At most, it could consist of singing "Ekesmaroot", "Hiten-ni", the hymn for the Trinity, "Ep ooro", the veneration for the saint of the day, "Khen ef Ran", Axios(a). So it could be done in 2-15 minutes depending on how fully. This is a little harder, but you can learn the hymns one at a time and add to it. You can find veneration hymns for many saints in "Melodies of the Distribution of the Holy Mysteries", also from the SUS.
Perhaps the most commonly done is to pray the Midnight Praise. This would mean praying the Midnight hour of the Agpeya, either after Compline, or very early in the morning, then praying the Midnight Praise, including any Psali for the saint of the day, and the doxology for the saint of the day. This is obviously the most time consuming, requiring 90 minutes to do properly. This is the hardest, as it requires learning a lot of hymns. You can get a good Psalmody book from the L.A. bookstore.
Many people also read the synaxarium entry and/or the readings for the day. Some people will also read an appropriate book, for example "the Life of Antony" on St. Antony's feast. Some of the youth at my church go crazy on St. Antony's feast. They go and pray the Agpeya, and the Vespers Praise, then they get the priest to raise the evening incense, then they'll have a veneration, then the pray the midnight hour, and the Midnight Praise, but then insert the reading of the Life of Antony in sections so that it takes all night, then the might sleep for a few hours, while some of them have silent contemplation, or more spiritual reading, then they'll pray prime and the doxology of prime, then the priest comes back to raise the morning incense and pray the Liturgy, so that they pretty much go from 7 pm - 8 am non-stop. Then the Virgin's feast is the same week, and no one shows up since they're too exhausted, which seems a little strange to me since our Church is dedicated to the Virgin. I'm not sure if they've moderated a bit in recent years... but that's pretty much everything that can be done
On the commemorations of Archangel Michael, it is also traditional to bake "fateer-malek", "angel's bread", like korbon, but sweet and oily, and give that to the poor. If you have an icon of the saint of the day, you can put that icon in a more prominent position while you're doing whatever you're doing, and light an oil lamp in front of it. Eastern Orthodox will also burn incense, but in the Coptic tradition this is forbidden to laity.
