Yes, as long as there are remaining available credit cards, you can spend them at any time, regardless of the billing date and repayment date;

Calculation of repayment date

2. If the future bill is credit card consumption (including the consumption on the repayment date), it will be included in the next bill and should be repaid before the repayment date of the next bill.
