My S planner has the holiday dates wrong, how do I correct this?

My s planner has the holiday dates wrong

All of the dates set for holidays on my S Planner calendar are one day early. I cannot even manually change those dates. Why is this and how do I fix it?

Re: My s planner has the holiday dates wrong

Which S-Planner calendar are you using, Samsung, My Calendar or Google?
Did it originally appear with the correct dates. Does it sync with your calendar web view.
I can't imagine what caused this.

If they are all individual dates you may have delete all and start again. I don't know how you could move all entries one day forward in bulk.

Have you checked the clocks on all synced devices?

Do you have a Locked Time Zone setting?

Maybe someone else has an idea.
