  • CELLSJAVA-41474 - Date calculation is wrong

I also used the Workbook.calculateFormula() but it did not change the results.

String filePath = “F:/Shak-Data-RW/Downloads/s.xlsx”;

Workbook wb = new Workbook(filePath);
wb.save(filePath + “.out.html”);


We have evaluated your issue further.
Well, “0” is MS Excel’s odd behavior for formatting DateTime whose numeric value is less than 1. You can try to format value such as 0.36 to “yyyy-mm-dd” in MS Excel manually, then you will get the strange value i.e., “1900-01-00” where the day is “0”. That is also the formatted result you got by MS Excel for your situation. However, for us, I am afraid it is impossible to get the formatted day as “0” for any valid DateTime value by program. So we cannot give the same result as MS Excel does in that case.

Thanks for your understanding!
