Our basic rule:

If it isn’t on the calendar, it doesn’t exist.

But for getting places on time, there’s an important second rule:

Don’t only put the START time.

An entry that says:

Dance — 5:00 PM

still makes me do mental math at 4:37.

Instead:

Dance — 5:00 | LEAVE 4:35 | Dance bag + water

Now the calendar contains the information I actually need.

Put the Logistics With the Event

Whenever possible, include:

START TIME

LEAVE TIME

LOCATION

WHAT TO BRING

And anything unusual.

For a birthday party:

Ava’s Party — 2:00 | Leave 1:25 | Gift + socks

That’s a much better note to Future Me than:

Ava Party 2

Your calendar should reduce the amount of thinking you have to do later.
