February 23, 2020 was Transfiguration Sunday.

However, some traditionalist Episcopalian clergy dispute that, pointing to the Feast of the Transfiguration on August 6:

That’s all well and good, but most observant Christians are more likely to be in church on Sunday than on a weekday.

These were among the replies that the Revd Everett Lees received:

Agree fully.

A Canadian wrote in:

Easy mistake to make, when in our Canadian Book of Alternative Services we have Transfiguration readings that day, and we’re directed to use the Collect for the Transfiguration. Personally, I don’t think God will lose too much sleep if someone calls it Transfiguration Sunday.

So did a Lutheran:

I guess my Lutheran Book of Worship: Manual on the Liturgy is wrong.

And what about denominations that do not observe feast days, e.g. the Presbyterians?

The aforementioned Rev. Green Man did a bit more research on the scheduling of Transfiguration Sunday:

Yes, that is helpful. I had not thought about the transition in Jesus’s ministry from Galilee to Jerusalem.

It should be noted that the Vanderbilt Divinity lectionary page has no list of readings for August 6.

From this we see that Transfiguration Sunday has its rightful place at the end of the season of Epiphany.
