Normally Datawrapper creates nice date intervals out of my time data, but not this time.

These problems occur when the data is uploaded in a way that makes it impossible for Datawrapper to interpret them correctly as dates:

• The data is not in a clean format. Follow our guide for clean data. There, we explain how your data should look like to be imported well with Datawrapper. For example, make sure you don't have a double-row header, but just one header row with labels.
• Dates are not recognized as dates: If numbers or dates appear as left-aligned and black in step 2: Check & Describe, Datawrapper recognizes them as text instead. Visit this article that explains how Datawrapper interprets date types and find a list of recognized date types here. 
• Special characters: Try to search for hyphens or slashes in your date cells and delete them.
