There is a new CIT 0002 (10-2020) form. As you may see question 9a) asks you : Enter the "To" Date from the Calculator. Then it shows the elegibility period one year time frame. IE from 29/03/2016 to 29/03/2021. However, this Eligibility period is not the as per the Online Calculator which says 30/03/2021 to 29/03/2021. As you can see there is a one day difference. This is because the new 0002 form does not let you input the starting date and it automatically calculates one year while the Online calculator uses one day less.
