The page cuts off my ability to select a date and time to attach to any project and or task.
please clarify what issue are you experiencing with Todoist. It's not possible to add a date or time to a project, only to tasks.
To add a date to a task, please click on it with the left mouse button and then either type the date in the date box in the lower-right corner of the input box (you can use "natural" dates such as "today" or "every 3 days") or pick the day from the drop-down calendar which will appear once you click on the date input field.
Also, by describing the issue you're experiencing, please try to mention step-by-step how to reproduce it. You're welcome to send a screenshot to firstname.lastname@example.org
