Calculate the contract or employment notice period end date from a start date and notice duration in business or calendar days.
Notice periods are required in many contracts and employment agreements before termination takes effect. Whether you are resigning from a job, ending a lease, or cancelling a vendor contract, you need to know exactly when the notice period expires.
This calculator determines the end date of a notice period by adding the specified number of calendar or business days to the start date. Business day calculations skip weekends, while calendar day calculations count every day.
Proper notice is often a legal requirement. Failing to provide adequate notice can result in breach of contract claims, lost security deposits, or forfeiture of severance packages. Knowing the exact end date helps you plan transitions and avoid costly mistakes.

Calendar Days: End Date = Notice Date + Notice Period Days Business Days: End Date = Notice Date + (skip weekends until business days counted)
Result: Notice period ends: March 11, 2026
Starting February 9, 2026, adding 30 calendar days results in March 11, 2026. If using business days, the end date would be March 23, 2026 (skipping 8 weekend days).
Employment notice periods protect both employer and employee. The employer has time to find a replacement, and the employee has job security during the transition. Senior roles often have longer notice periods (60–90 days) to allow for knowledge transfer.
Residential leases typically require 30 days notice before the end of a lease term for non-renewal. Month-to-month tenancies usually require 30 days notice to vacate. Commercial leases may require 90–180 days.
Always give notice in writing. Use certified mail, email with read receipt, or hand-delivery with a signed acknowledgment. Document the date notice was given and the calculated end date to prevent disputes.
Employment notice periods typically range from 2 weeks (entry-level) to 3 months (executive). Lease notice periods are usually 30–60 days. Vendor contracts may require 30–90 days written notice.
