About Notice Period Calculator
Resigning professionally requires knowing exactly when your notice period ends. The Notice Period Calculator takes your notice start date and the length of your notice in weeks, then returns your last working day and the total number of calendar days in the notice period. This is particularly useful in jurisdictions where standard notice periods range from one week for recent hires to three months for senior roles, and where employment contracts often express notice in weeks rather than days. Getting the date wrong can delay your start at a new employer, affect final paycheck calculations, or create tension with your current manager. For example, if you hand in notice on Monday, June 17, 2026 with a four-week notice period, your last working day falls on Monday, July 15, 2026—assuming weekends are non-working. The calculator also adjusts the final date to the preceding Friday when it lands on a weekend, matching common corporate practice. Knowing these dates in advance helps you plan knowledge transfer, exit interviews, and the first day at your next role.
How It Works
Enter your notice start date in YYYY-MM-DD format and your notice period in weeks. The calculator multiplies the weeks by 7 to get calendar days, then adds that number to the start date. If the resulting last day falls on a Saturday or Sunday, it rolls back to the preceding Friday to reflect a standard Monday-to-Friday work week. The tool also reports the total calendar days counted, which is useful for contract verification.
Formula & Calculation Logic
Total Notice Days = Notice Weeks × 7. Last Working Day = Start Date + Total Notice Days, adjusted backward to Friday if the result is Saturday or Sunday. The tool counts calendar days, not business days, and does not subtract public holidays or personal leave.
Step-by-Step Guide
- Step 1: Enter the date your notice officially starts, typically the day you submit your resignation letter.
- Step 2: Enter the notice period specified in your contract, in weeks.
- Step 3: Review the total number of calendar days in the notice period.
- Step 4: Check the calculated last working day.
- Step 5: If weekends are non-working, confirm the auto-adjusted Friday fallback.
Example Calculations
- Scenario 1: Starting notice on June 17, 2026 with a 4-week period gives 28 calendar days and a last working day of July 15, 2026.
- Scenario 2: Starting notice on June 20, 2026 with a 2-week period lands on July 4, 2026, a Saturday; the calculator adjusts the last working day to Friday, July 3, 2026.
Common Use Cases
