This market resolves to YES if the average daily passenger volume across all transportation modes during the 15-day Mudik period (H-7 to H+7) for Idul Fitri 2025 (24 March - 7 April 2025) is LOWER than the same period for Idul Fitri 2024 (3 - 18 April 2024).
Mudik is the annual mass exodus when millions of Indonesians travel from urban centers to their hometowns for Idul Fitri. Resolution will be based on official Kemenhub (Ministry of Transportation) passenger statistics published at https://strategi.kemenhub.go.id/landing/rutin/pergerakan-penumpang?menu=all or equivalent official government source.

So establishing some base rates, comparing 2024 and 2025 for D-45 to D-15 Lebaran (Idul Fitri), which in 2024 falls between 25 Feb - 26 Mar 2024 (Lebaran @ 10 Apr 2024), and in 2025 falls between 14 Feb - 16 Mar 2025 (assuming Lebaran @ 31 Mar 2025), the result seems ... inconclusive? some days in 2025 have a higher volumes of passengers and vice versa, like so

A viz with Python, (with 2022 & 2023, Lebaran @ 2 May 2022 & 21 Apr 2023) ...
