I have always struggled to convert AH dates to AD dates and vice versa. Although there are converters online, it is cumbersome to determine exactly when a particular regnal year starts and when it ends.
I have written a computer script (in Python) which prints the start and end of all of Aurangzeb's regnal years, with dates given in both AH calendar and AD calendar. Please share your feedback, and let me know if you spot any errors. I am using Aurangzeb's reign first for verification, others will follow. The full reign is in the pdf file, image shows a snapshot. Thanks!
