Get the month for billing period in billing schema.

Hi experts,

My client is having monthly billing cycle. so, billing period starts on 1st of every month and ends on 30th or 31st of that month. Now, I want to have the value of my current billing month in my schema.

Let's I am doing billing of June month, I want to get the value June in billing schema. Is this possible via any standard variant program?

Thanks
