My Last Day

Work fewer. Quit smarter.

My Last Day is a location-aware resignation planning tool that helps users find the best day to quit based on their notice period, public holidays, weekends, and working-day assumptions.

Unlike a basic notice period calculator that only estimates one end date, My Last Day compares multiple resignation dates and highlights the option with the fewest Working Days Left.

Why I Built This

Most notice period calculators answer:

"When does my notice period end?"

But many people actually want to know:

"What's the best day to quit?"

My Last Day helps users compare resignation dates and understand how weekends, public holidays, and notice periods affect:

• Last Working Day
• Official Last Day
• Working Days Left

The goal is to provide a fast, transparent, and low-friction planning experience.
