We can add a dropdown like that:

Also custom durations longer than 480min would be great.
Could be used as booking calender for multiple days as well.

@CarinaWolli Is this supposed to be a front end/ cosmetic change only, like you are able to input minutes, hours, days via the dropdown but behind the scenes it gets converted to minutes and remaining flow remains same.

This is the first issue I stumbled upon here, and I implemented a rough version of what I said above, still need to familiarize myself with the entire codebase ofcourse.

Subject: Request to Collaborate on an Issue for a University Project

Dear Cal.com Team,

I hope this message finds you well. My name is Felix Arnos, and I am a university student from Simon Bolivar University. As part of a university assignment, my team and I (a group of five students) are required to contribute to an open-source project. We have chosen Cal.com because we admire the work your team is doing and believe it aligns well with our learning objectives.

We are currently reviewing the open issues in your repository and would like to contribute by working on Request for hours to be added to event duration options #16958. Would it be possible to assign this issue to our team? We are committed to following your contribution guidelines and ensuring the quality of our work.

Please let us know if there are any additional steps we need to take or if you have any recommendations on how we can best assist the project.

Thank you for considering our request. We are excited to contribute to Cal.com and look forward to your guidance.

Best regards,
Felix Arnos
