16 free calculators for the “exactly which day” questions in the immigration process: the earliest date you can file, when your status expires, how a waiting period is counted. Each tool cites the rule it is based on, so you can check the result yourself.
These tools calculate dates and deadlines and are not legal advice. Individual cases have exceptions; if you are unsure, consult an immigration attorney.
