About Rosh Hashana that Begins the Sunday Evening after RE
If you are concerned about the fact that Rosh Hashana starts the Sunday evening after the end of RE 2019, consider celebrating Rosh Hashana in Seoul, attending services either at the Chabad House or at the US Military Base. See Korea for expatriate for more information, including whom to contact. While I am not certain about the US Military Base's having services, I am certain that Chabad House will have services.
