I have two dates
1.statdate : 12-11-2022
2.enddate. : 02-20-2023

if the start date is **1-15th** day then the result should be the current month ex: `mm-dd-yyyy[12-11-2022]` Then December 1st
if the start date is **16th-31st** day then the result should be the current month EX: `mm-dd-yyyy[12-22-2022]` Then January 1st.


if the EndDate  is 1-15th day then the result should be the current month+1 EX: `mm-dd-yyyy[02-11-2022]` Then January 31st
if the EndDate  is 16-31sh day then the result should be the current month+1 EX: `mm-dd-yyyy[02-20-2022]` Then Feb 28th

input **start date result:** December 1st 
input **end date result:** Feb 28th
Result[3] which is three months from the start date to the end date.

Can we do this in the formula field? I am able to do it in apex it worked but I was unable to do it in the formula field any help would be appreciated.
