[Android Central Question]

how can I sync Galaxy J3 Emerge calendar with my windows 10 calendar without using outlook?

Welcome to Android Central! Which calendar account on the phone are you using -- the local Phone account calendar, or a Google account calendar? If it's the former, that's often more trouble than it's worth. There's no true sync between that calendar and the Windows 10 Calendar app -- you'd have to find some clunky workaround app.
