Problematic UI change in Dashboard calendar

Hi, my name is Nan.

I want to report a not so recent (maybe a month ago) change in the dashboard calendar behavior, which causes problem to the way we use dashboard in our company.

How we use the dashboard:
In our dashboard, we have a widget for task assigned to individuals with "status = DOING" and "last modified date" filter set to [begining of time] ~ [today - 2 weeks]. This is used to display tasks where it is still active and yet no update was made in the last weeks. So kinda like "forgotten tasks".

What Changed:

The image above is the new calendar UI in dashboard. In order to set start date and end date several years apart, I have to click the month scroll icon many many times. I can't remember how it was before, but I could definitely do it in few clicks.

What I wish:
Simply, please change it back to the way it was. The UI isn't even consistant with the calendar UI for task view, as shown below. Here, at least I can type in the date.
