The Notice Drill
Missed deadlines and short notices end claims and tenancies. Here is a skill that is easy to state and easy to get wrong: counting working days, skipping holidays and weekends, and counting months by the calendar. Every problem is generated fresh, so you can drill as long as you like.
The rules (they stay the same in every problem)
- A landlord ending a periodic tenancy must give the tenant not less than the period the tenancy requires, in writing.
- A notice delivered by hand is served on the day it is delivered.
- A notice sent by post is deemed served on the second working day after posting. Saturdays, Sundays and public holidays are not working days.
- The period runs from the day of service. A period of months ends on the same day of the month, that many months later (if that month has no such day, on its last day). A period of days is counted forward from the day of service.
- A notice is valid if the end date it states is not earlier than the earliest end date that calculation gives.
All places, dates of public holidays and laws are fictional (the Republic of Eastmark). No calculator is needed, only a calendar and care.
Problem 1 of 5 · drill 1001
A landlord’s written notice to end a periodic tenancy was posted on Monday 6 October 2025. The tenancy requires not less than 28 days of notice. The notice says the tenancy ends on Sunday 9 November 2025.
Public holidays in Eastmark that week: Founders’ Day, Wednesday 8 October 2025; Harbour Day, Friday 10 October 2025.
An experiment with your own AI
Copy the rules and a problem into an AI tool you use and ask it the three questions. Compare its answers with the working above. Date arithmetic, working days and calendar months are exactly where confident-sounding answers go wrong, which is why a lawyer checks them by hand.
