Get Last day of a month (28, 29, 30 or 31)? Formula DAY(ADDMONTHS(DATE(YEAR(DateField__c), MONTH(DateField__c),1),1)-1) The trick here is to take the 1st of the month and year of the date field, add 1 month to it and subtract 1 day. For example, if my date field is March 3rd 2022, the formula will add 1 month to March 1st 2022 and will return April 1st 2022. We then subtract 1 day to get March 31st 2022.
