Lease renewal deadlines deserve a calendar.
Enter your lease expiration date and contract notice timing to estimate potential option dates. Nothing is uploaded or stored by this calculator.
One missed notice can change your negotiating leverage.
A dental or medical lease may require written notice months before the space actually expires. Renewal-option provisions can also include an earliest delivery date, a strict method of service, and limits on how or when an option can be exercised.
This calculator estimates notice dates from the timing assumptions you enter. It does not read your lease and does not know whether your landlord must receive the notice by a specific date.
Before relying on any timeline, check:
- Is the provision a renewal option, an early termination option, or an ordinary negotiation opportunity?
- Does the lease specify calendar days, business days, or calendar months?
- Is notice due at least a certain time before expiry, or only within a specific notice window?
- Must notice be received by the landlord, mailed to a specified address, or delivered by an approved method?
- Are there lease-default or personal-guarantee conditions affecting the option?
