Incorrect Date in Web

hello community,

I am new here and also a new Power BI user, I am very impressed with the tool.

But I have a problem, a date field from the database is displayed correctly in the desktop app, but I always see date-1 on the web.

Example:
Correct date should be 01.05.2020 (DD.MM.YYYY)
on the web, however, is displayed 30.04.2020

This is a huge problem because the month in the filter is then no longer May, but April.

The date comes from the database as a time stamp
I format the date like this:
DateTime.Date([Date_created])

Can you tell me what I have to do differently?

Thank you very much
