Hi Anita,

Yes, there is a formula you can use to calculate the percentage of the month that has passed. Here are the steps:

1. First, you need to determine the total number of days in the current month. You can do this by using the
   Formula:

   EOMONTH 

   function. For example, if you want to calculate the percentage of days that have passed in the current month, you can use the following formula:
   
   =EOMONTH(TODAY(),0)-DATE(YEAR(TODAY()),MONTH(TODAY()),1)+1
   
   This formula will give you the total number of days in the current month.
   
2. Next, you need to determine the number of days that have passed in the current month. You can do this by using the
   Formula:

   TODAY 

   function to get the current date, and then subtracting the first day of the month from it. For example:
   
   =TODAY()-DATE(YEAR(TODAY()),MONTH(TODAY()),1)+1
   
   This formula will give you the number of days that have passed in the current month.
   
3. Finally, you can calculate the percentage of the month that has passed by dividing the number of days that have passed by the total number of days in the month, and then multiplying by 100. For example:
   
   =(TODAY()-DATE(YEAR(TODAY()),MONTH(TODAY()),1)+1)/(EOMONTH(TODAY(),0)-DATE(YEAR(TODAY()),MONTH(TODAY()),1)+1)*100
   
   This formula will give you the percentage of the month that has passed.
   

To calculate the percentage of the month left, you can simply subtract the percentage of the month that has passed from 100. For example:

=100-(TODAY()-DATE(YEAR(TODAY()),MONTH(TODAY()),1)+1)/(EOMONTH(TODAY(),0)-DATE(YEAR(TODAY()),MONTH(TODAY()),1)+1)*100
