Help with visualizing operating hours of public facilities using OneMap API?

Hi everyone,

I’m working on a small prototype to visualize opening/closing hours of public facilities (like parks, clinics, and libraries) using OneMap data and time-based filters. I’m able to retrieve POIs via API, but I’m not sure how to best structure or query by operational hours, especially when the hours vary across weekdays and weekends.

Has anyone tried implementing a time-aware layer or used an approach that lets users filter POIs based on current time (e.g. “what’s open now”)?

Appreciate any insights, examples, or even relevant datasets I might be missing.

Thanks in advance!
