Notice periods, what the dates actually mean
A notice period sounds simple until you count it. Two weeks can mean 14 calendar days or 10 business days depending on who is reading, and the difference decides your last paycheck, your benefits cutoff, and your start date. Put the exact date in writing and there is nothing to argue about.
What two weeks notice actually means
Usually 14 calendar days from the day you resign, but some companies count 10 business days, which lands later if a weekend or holiday intervenes. Companies read it differently, so do not leave it to interpretation: name the exact last day in your resignation letter.
At-will employment in plain terms
For most US roles, notice is a professional convention, not a legal requirement. Either side can end at-will employment at any time. Employment contracts, offer letters, and handbooks can set different terms, so check yours before assuming two weeks is enough or required.
How to phrase the effective date
Write it as a specific date, not a duration: "My last day of employment will be Friday, July 24, 2026." A dated sentence removes ambiguity about whether the notice day itself counts and gives payroll and HR one number to work from.
The company may end it early
Some employers accept a resignation and release you the same day or put you on garden leave, especially in sensitive roles. In at-will states they generally can, and they may not pay out the remaining notice. Plan your finances for the possibility that your last paid day is the day you resign.
