I was working with a client this week about issuing a 60-day notice and timing the notice to expire at the end of March. I turned to my Date Ranger App on my iPhone to calculate the days. I thought January 30th would be my last day to serve a 60-day notice that would expire on March 31st. But I was clearly mistaken. My app came up with March 30th. How could that be? Then I saw the calendar and noticed the mysterious February 29th. This black sheep of the calendar family only shows up once every four years, and it had mysteriously found its way into my 60-day notice calculation.

So for all those that are giving 30-day or 60-day termination notices of any kind, beware of the following dates:

• For 30-day notices that you intend to expire at the end of February 2016 (the 29th this year), you need to serve the notice no later than January 30, 2016.

• For 60-day notices that you intend to expire at the end of March 2016, you need to serve the notice no later than January 31, 2016.

• For 90-day notices that you intend to expire at the end of April 2016, you need to serve the notice no later than January 31, 2016.

You can get date and time calculators for your smartphone from the app store. There are also free websites that will calculate days for notices.
