Based on Rose Guide to the Tabernacle. There are ways to create pie/doughnut calendar charts on excel, etc., but I do not have the time now.
However, I believe that such pie chart is the best representation of the Jewish Calendar.
Nisan (Mar-Apr) Iyar (Apr-May) Sivan (May-Jun) Tammuz (Jun-Jul)
Av (Jul-Aug) Elul (Aug-Sep) Tishri (Sep-Oct) Heshvan (Oct-Nov)
Kislev (Nov-Dec) Tevet (Dec-Jan) Shevat (Jan-Feb) Adar (Feb-Mar)
- Nisan marks the Ecclesiastical New Year.
