# Continuing the calculation at Jupyter Notebook on another day

I'm running a function at Jupyter Notebook which might cost more than 5 hours to be completed in my estimate.

When we play games, we don't usually complete every mission just in one day but save it at some point, and continue it on another day.

Likewise, to stop and save the calculation at some point and continue the calculation from that saved point on another day, what would be the necessary steps that I must follow?

If I look at menu bar in the upper side, I see 'Run' button and '■'(black square) button next to it.

Would pressing the '■'(black square) button enough to save the calculation? After saving it, if I load the file on another day and press the 'Run' button, would it continue the calculation from the saved point and not restart the whole process again?

For example, if there is a task that costs 5 hours, saving it at some point after calculating it for 4 hours, and loading it on another day to continue and finish the remaining 1 hour of task,

would this happen by just pressing 'Run' and '■'(black square) as what I mentioned above?

If not, I would like to know whether there is any way to do this.

Thanks.
