In TickTick, date & time information you type in the name of your task will be recognized as the due date. A reminder will then be automatically created.
For example, if you want to go to library on October 30 at 2 p.m., just type: "Go to library Oct 30 2 pm" when adding a new task. TickTick will automatically recognize October 30 as the task's due date and set a reminder at 2 p.m. on that date for you.
How to remove the date & time info from task content when using Smart Date Parsing
Go to Settings > Preferences > Smart Recognition > Date Recognition > Choose Remove text in tasks
