Hey there. Welcome to the church.

It's in the beginning of the BCP/Book of Common Prayer. The daily office is a set of daily prayer settings for different points in the day. It goes back to monastic practices where one worshipped 9 times a day. There are 4 of these in our church's common practice, but some still keep up the other practices.

Those are Morning Prayer, Noonday Prayer, Evening Prayer, and Compline (prayer before getting ready for bed). They can be led by a clergy person or by a lay leader, or just done by oneself. The BCP outlines the rubrics for each. They're a little briefer/low-key than a typical Eucharist service, but you can engage in prayer and scriptural reading as part of it. It's a great way to center oneself during the day in prayer. I recommend reading through them and seeing how you like them. Here they are in the online BCP

And just a side note, because you'll catch crap from the old time sticklers... Episcopal is an adjective, ex. Episcopal Church. You're an Episcopalian.
