Always ensure your repayment date sets you up for a stress-free repayment. You could, for example, align it with your income, such as your salary, expected business income or allowance, etc. By aligning your repayment with your salary, you will ensure you can repay on the date you selected and keep your interest to a minimum.
For example, if you receive your income on the 30th of each month, then you should target to repay immediately after the 30th.
