Issue with Proration Calculation in YITH WooCommerce Subscription

Hi everyone,

I’m using the YITH WooCommerce Subscription plugin on my WooCommerce store to manage monthly subscriptions. The system is configured to prorate the subscription price if a customer subscribes on a date other than the start of the billing cycle, which is set to the 1st of each month.

However, I’ve noticed an issue with the proration calculation: the plugin seems to assume that all months have 30 days. This creates discrepancies in months with 31 days (and possibly in February), resulting in the charged amount being slightly inaccurate. This is problematic for me because my invoicing software calculates based on the actual number of days in the month, and the amounts do not match.

Although the difference is minimal, I’m concerned that this could cause issues in the long run, both internally and with customers.

I’ve reviewed the plugin settings but haven’t found any options to adjust this calculation. I’ve also updated to the latest version of the plugin, but the issue persists.

Has anyone else encountered this problem? Is there a way to fix the proration calculation so it considers the actual days of each month? Any guidance or solutions would be greatly appreciated.

Thank you in advance for your help!
