Common questions
What does the App compute?
Count backward from travel through processing and mail buffers to a mail-by target date.
What does the App not do?
This App counts days you enter. It does not check your eligibility, complete forms, or reflect live processing times.
Where do the numbers come from?
You enter every number yourself. The sources support the method and the limits. They do not produce a result for your specific case. Keep the original documents next to the sheet you build.
