It depends on when your salary is paid.

I think according to the above table, you can choose any accounting date from 25th to 26th, and you can also choose 1.

My intuition tells me that I should choose the 25th or 26th.

Because if you do this, assuming that the billing date of your ICBC card is 25th, the billing date distance between the two cards is at least 1 1(25- 14) days.

Or 12 days (26- 14)

If the billing date is on 25th or 26th and the repayment date is on 18 or 19, then the due repayment date between your two credit cards is the shortest.

(2/ 18-2/3) 15 days, and the longest 16 days is enough.

The longer the bill date is delayed, the more cost-effective it will be for you, because you don't have to worry about receiving or paying the repayment amount of two bills in the shortest time. Similarly, the longer the due repayment date is delayed, the better for you.

The more bills you have in a short time, the more money you have to pay back, and the repayment pressure will be greater for you than when the bills come.

Of course, the person who makes the final decision is yourself, and my suggestion can only be used for reference.
