[Android Central Question]

We got a complaint from a client saying that his calendar is not syncing properly. Any event he creates on a shared calendar is off by one full day early. This apparently is only happening on his Samsung Note (don't know model #). So I tried to recreate the issue using my Note 9 and lo and behold, the events are off by one full day early. A co-worker tried to recreate the issue on his LG, but it displays the events correctly. I tried to re-create the issue on an iPad, but it also displayed the events correctly.
The client is using Outlook 2013 to create the events and the server is Exchange 2016. has anyone heard of or had experience with this issue? Is it a Note problem?

It appears to be a Samsung problem for all day events. Since dates are stores as Unix timestamps, "all day" is displayed as 00:00:00 on the day in question. Evidently, Samsung's version of Calendar interprets that as midnight of the previous day. (I can't fault Samsung for that - many, many programmers have gotten bitten by that. I always considered "midnight" to be 00:00:01, just to avoid that possibility. A calendar being 1 second off is nothing, but having it interpreted as one day off is bad.)

Not much your client can do except make an all day "event" start at one second (or one minute) past midnight, and end at 1 second (or one minute) before the following midnight.

If the problem is with all events, not just "all day" ones, then Samsung has really messed up.

It's not just items that are added as events. I just went into my calendar to add something and saw that Thanksgiving is now listed as Wednesday and not Thursday. Then I saw some other events that had been pulled from my calendar that are off a day. I went in and fixed that I'm just wondering how many others are off. Never had this problem before why is it happening all of a sudden?

Just an FYI. I went in to look at my calendar and noticed that it's the Hotmail / Outlook calendar that is off. So I turned it off.

Sounds like an outlook or settings issue.
My Samsung calendar has Thanksgiving on Thursday.

Perhaps outlook is on the wrong side of the international date line.
