How does a monthly Shopify subscription cycle work?

How does Shopify Subscription work? If i get a subscription on 30th of the month, will my subscription for that month expire by 1st of the next month?

Shopify bills you every 30 days, so the date which your payment will be processed (and to which it expires) may change depending on if a month has more or less than 30 days.
