Batman Day does not have one fixed calendar date every year; it is usually celebrated on a Saturday in September, most often the third Saturday, with the exact date announced annually by DC.

Quick Scoop

  • Batman Day is an annual celebration created by DC Entertainment to honor Batman.
  • The first Batman Day was held on July 23, 2014, tied to Batman’s 75th anniversary at San Diego Comic-Con.
  • Since then, the event has typically been scheduled on the third or sometimes fourth Saturday in September, rather than a fixed numerical date.
  • For example, some recent and upcoming observances are:
    • 2024: widely marked on Saturday, September 21.
* 2025: DC has promoted Batman Day as Saturday, September 20, 2025.

So, when is Batman Day?

Because it’s a branded celebration rather than a governmental holiday, DC and partner sites announce the specific date each year, but you can safely think of it as:

Batman Day = a Saturday in mid‑to‑late September, usually the third Saturday.

If you want the exact date for a particular year, it’s best to check DC’s official announcements or event calendars as September approaches for that year.
