Today is May 15, 2025. Since you asked how many more days until May, and we are already in May, the answer depends on what you mean:

• If you mean how many days until the next May (May 1, 2026) , that would be:

From May 15, 2025 to May 1, 2026 is 351 days.

• If you mean how many days until the end of May 2025 , there are 16 days left (including May 15).

Could you please clarify which one you meant?
