Is there a better computer desktop clock calendar software?

Regarding the relatively easy-to-use computer desktop clock calendar software, it is suggested to use the dedication sign. Although the special post-it note is a post-it note software, the memo recorded on the post-it note can be reminded by setting the time.

You can set a time reminder for the contents of the memo recorded on the dedication sign, and support single reminder, periodic reminder, important event interval reminder and overdue reminder;

Dedication sign supports setting reminders according to Gregorian calendar date and lunar calendar date;

The to-do items recorded in the dedication notes can be classified, and 500 items can be entered under each category, and 500 words can be entered in a single note.
