Is there a browser extension or a program for windows that will display reminders on the screen at specified time intervals?

Question

Google Chrome

Hello.
Is there an extension for the browser (Chrome) or a program for Windows that, at specified time intervals, will display notifications (reminders) written by the user to himself?
It will be very good if this extension will display alerts on a new browser tab.

Answer 1

Standard task scheduler - add a task, specify the frequency of launch, as an action, specify the opening of the desired html file in the desired browser.

Answer 2

Full of reminders. It is not particularly clear why to display the prompts in the tab.
I can understand, for example, the desire to have a program that fills Google calendar reminders so that they pop up not only on a PC, but also on a phone. But why in a browser?
I myself use the clock in the 1st clock tray, set it up so that by double-clicking on the clock, the window for creating a reminder immediately opens. The settings there are wide, you can assign it to a specific time, or at a specified frequency, hang programs on it, etc. When a reminder is triggered, it can be reset / postponed to the desired time. A bonus to this is a normal clock in the tray, with the richest settings, but without idiotic skins, like Atomic alarm\Chameleon clock.
It costs money, but it is on the rubord.
