Halloween output has grown three years in a row, from 57 releases in 2023 to 74 in 2024 and 106 in 2025. Day of the Dead has stayed in a narrow band of 24 to 29 titles a year.

SlotCatalog · monthly releases per theme, January 2023 to 10 October 2026
The release calendar is shifting. From 2023 to 2025, 73% of Halloween releases landed in September and October, and October 2025 alone brought 60 titles, about two a day. In 2026 the pattern changed: 42 Halloween slots launched between January and August, against 15 in the same months of 2025. February 2026 alone had 11. Day of the Dead moved the same way, with 21 releases from January to August 2026 against 10 a year earlier.
Both themes are running ahead of 2025. By the end of September 2026, 57 Halloween titles had launched, against 32 at the same point in 2025. Day of the Dead stood at 23 against 15. By 10 October, Day of the Dead had 25 releases, one short of its full 2025 total, while Halloween’s 70 equalled 66% of its 2025 count. From October to December 2025, another 74 Halloween titles followed. Half that pace after 10 October would take 2026 past 106 and set a new record. Day of the Dead needs five more titles to pass its 2023 high of 29; it added at least 11 in every October to December of the period.
The year-to-date ratio of 2.8 : 1 flatters Day of the Dead. Most of Halloween’s October volume still lies ahead, so the full-year gap is likely to widen again.
In SlotCatalog’s 2023–2025 export, Halloween made up 17.87% of the 1,399 seasonal slots across nine holiday themes. That is above the 15% level our St Patrick’s Day analysis identified as the point where added volume stopped producing visibility. Day of the Dead, at 6.00%, sits in the same low-density band where Easter grew.
