This is an application that sets the standard date and time, and can calculate the days after and days
before.
For example
48 days after September 2, 2019
October 20th, 2019 (Sun)
And so on.
This is especially useful when you want to know the dates across months.
The app is automatically set with today's date, but you can change it to use it.
Enter the number of days, select "Days after" or "Days before", and press the "Calculate" button to
answer.
The history of calculation results is automatically saved and you can check up to 10 records.
