Important dates should be remembered. However, due to some unfortunate circumstances, these special days tend to slip out of our minds. So, we must track these dates. We must have a planner to turn to if we don't want to forget these rare occasions.

If you still don't have an application that can help you with this problem, the OI Calendar Picker app can be of great help. This program helps you select a date from a calendar or a time from a time range. This way, you get to visualize the timeline-based plans that you have in mind.

Note that this is an extension of another app and will not launch by itself.
