About Rosh Hashanah that Begins the Sunday Evening after RE
If you are concerned about the fact that Rosh Hashanah starts the Sunday evening after the end of RE 2019, consider celebrating Rosh Hashanah in Seoul, attending services either at the Chabad House, at the Chabad Jewish Community or at the US Military Base. See Korea for expatriate for more information, including whom to contact. You can check the detail information and make a reservation to the Chabad Jewish Community in the hompage. While I am not certain about the US Military Base's having services or only permitted to the US Military related person, I am certain that Chabad House and Chabad Jewish Community will have services.
