Radar with Date Axis
Date-based data for cyclical periods (months, years, etc.) is well suited to be depicted in a Radar Chart. amCharts flexibility enables you to use date axes in a circular fashion with little effort.
Key implementation details
We add our regular DateAxis to the Radar Chart and just set its renderer to AxisRendererCircular.

Create a radar chart with a circular date axis spanning January 1, 2021 to January 1, 2022 (daily intervals) and a radial category axis with 5 categories ('One' through 'Five'). Display 5 separate column series (one per category), each showing multiple date-range segments as rounded column bars representing events with start and end dates. Allow overlapping segments within the same category. Add a cursor with zoom and both horizontal and vertical scrollbars. Configure tooltips showing the category and date range. Set a donut hole for a ring appearance. Disable panning; enable mouse wheel for panning and zooming. Animate on load. Use amCharts 5 library.
