Daily Scripture differences - GOARCH vs other jurisdictions?

[SalemsConcordance]

I found today the app DailyReadings (which is from GOARCH), and the GOARCH website have a different Epistle reading from the other dioceses. Is this a normal thing? I've kind of spot checked a few random churches, but can only see this difference in Greek diocese and not the others like OCA, Antiochian and the Russian Orthodox

Online Chapel - Greek Orthodox Archdiocese of America

• Epistle Reading: St. Paul's First Letter to Timothy 6:11-16
• Gospel Reading: Luke 20:46-47; 21:1-4

Is this normal to have some daily scripture reading discrepancies?

2 Timothy 3:1-9
Luke 20:46-21:4

Scripture Readings

• 2 Timothy 3:1-9
• Luke 20:46-21:4

I don't think its old / new calendar, another church under the EP of Constantinople its the same as 1 Timothy 6:11-16

My readings that I got in a little book from my Church are the same as the GOARCH ones.

Personally I don't know why it differs, but the main thing is that you are doing daily readings! I wouldn't trouble myself with it if I were you.

I've found that my OCA readings calendar differs occasionally through the year from the commentary I use. Don't know why. I follow the calendar, and flip around a bit in the book.

yes, they are different, which is fine. certain saints and readings take precedence depending on where you are because of how Orthodoxy organically grew in each unique area.

It’s been major torture for me, trying to square readings, and podcasts of readings, especially for my kids on Sundays and holidays, between what actually goes on in my church, and what resources in English are available. “The Path” with Fr Tom Soroka is awesome, but rarely lines up. “Let Us Attend” lines up only half the time. Never mind that on my Sunday morning, the latest podcast might be for the last Friday or last Sunday.
The most helpful has been the app from Holy Trinity ROC in Baltimore, but I still get only an 80-90% alignment rate. I wonder why over all this time some good Orthodox programmers can’t produce a good app that would let you identify a parish and diocese, and then figure out what is appropriate for that day in that diocese.
