1. If interest is calculated on a daily basis, it means that the head does not count as the tail or the tail does not count as the head.
For example, 20 1 0.8.30-2010.8.31yes1day;
2. If the interest is calculated monthly, it will be calculated monthly.
If the loan date is 20 10.8.3 for three months, it is 2010.1.3;
The loan date is 20 10.8.30 for three months, that is, 2010.1.30.
If the loan date is 20 10.8.3 1 0.1.30.
If the loan date is 20 10.2.28 for three months, it is 20 10.5.3 1.
The number of overdue days is calculated according to the actual number of overdue days, and the interest rate is /360 per year or/12 per month.
According to what you said, if it is "paid off within one month", it can be understood that the longest term is 1 month, and the interest is calculated on a daily basis;
If one month is agreed and the loan date is May 26th, the repayment date is June 26th.
Personally, if it is private lending, the premise is mutual trust; It's no use caring about a day and a half to make money.
