음력 달력이랑 연동이 필요합니다.

Sometimes we need to be reminded how many years for a Birthday or Anniversary. It would be very helpful if there was a place to mark to tell the program to calculate the number of years from the beginning date. A start date would be needed to calculate from.

This will help us to plan the calendar and fix appointment in the working days and avoid the non working days appointment.  if this feature already exit, please help me to turn it on

My use case:  I am in New York and have meetings next week in LA.  I need to see the LA times of the meetings for easier planning.  In fact, I am currently writing an email to LA colleagues about this, so I need to set OneCalendar to LA time to see my schedule while writing -- without having to go into Windows settings to change the whole device time.  I don't afterall want my email to have an LA time stamp, I just want to see the meetings correctly.  Sure I can just subtract 3 from what OneCalendar shows,

Could you hover tooltips above all buttons and other items with mouse-hover?

There is no tray icon in Win11 Businessand it cannot be activated.

I don't want to pin One Calendar to the taskbar.

Is it a bug? Or do I need to pay for the premium app to get in into the tray? Or is it something for a suggestion for improvement?

Right now, I am missing sometime events since I can only see a view of 9h-21h on my overview page.

A zoom out function is not available.

Could you add the ability to have the full day view (0-24h) and full week view (0-24h) on 1 page ?
