Is it a possibility HISD will extend the last day of school to make up for all these missed weather days?

Newish parent here. Do schools push back the last day of school due to missed days throughout the year? If so, how much warning do you usually get? I need to figure out childcare over the summer and don’t want to pay for days that I don’t need to. Currently, the last day is set for June 11th. TIA!
