To make sure there is no room for doubt, if you write the date in a sentence format such as “dated February 2nd, 20th,” then it is clear, on the date that the parties must write on the document. Some countries have a date first month/day/year, while others have the day/month/year. What are the important things you need to know! For example, if you are on February 10, you can write it as 02/10 or 10/02. It can be quite confusing depending on who reads the contract, because the reader may not know if we are dealing with February 10 or October 2.
