Calculate the difference between two dates and add the first and last day

Hey all! I have recently started using Airtable. I have two date fields that show the number of days between the two dates, and I want to add the first and last day

Hi @Abdelraouf_Alkady,
You always want to add two days to the difference? Or is there a time that the day of should count?

DATETIME_DIFF({Due Date},Date, 'days')+2
