Why calendars go wrong

Almost every calendar failure has one of five causes: a wrong time zone, a missing buffer, a double booking from an unprotected proposed time, a missing link or address, or a meeting nobody confirmed. This page closes all five.

Step 1: Write the calendar rules

Agree these with the client in week one and store them in the Client Workflow Record.

Working hours and time zone
Protected blocks (focus time, family time, gym, school run)
Default meeting lengths (for example 25 or 50 minutes, not 30 and 60, to leave natural gaps)
Buffers between meetings
Maximum meetings per day
Which meetings you may book alone, and which need approval
VIP list: people who may override the rules
Preferred meeting tool and whether the client hosts or joins
Travel preferences (airlines, seat, hotel style, budget limits)

Step 2: Protect time the moment it is proposed

When you propose times to someone, place a HOLD on the client's calendar for each option immediately, titled "HOLD: (TOPIC) with (PERSON)". This stops a second booking from stealing the slot.

When the other side picks a time, convert that hold into the real event and delete the other holds the same day. Holds older than 24 hours with no reply get removed and the contact gets a nudge.

Step 3: Buffers

Situation	Buffer
Video call to video call	10 to 15 minutes
Before an important pitch, interview or board meeting	30 minutes prep block
In-person meeting	Real travel time from a maps app at that time of day, plus 15 minutes
After a long flight	No meetings for at least 2 hours after landing, unless approved

Step 4: Time zones without mistakes

Set your calendar display to the client's time zone, not yours.
Every invite with people in different zones names each zone in the description: "2:00 PM ET / 11:00 AM PT / 7:00 PM UK".
When you write times in emails, always name the zone. Never write "3 PM" alone.
Clock change weeks are danger weeks. The US, UK and Australia change their clocks on different dates, and Australia moves in the opposite direction. In the weeks around March, April, October and November, recheck every cross-zone meeting.
When unsure, use a world clock tool to check, and write the date as a word (for example "Wednesday, 4 November").

Coach's note: for any meeting with three or more time zones, write the time for every person in the invite, even if the calendar shows it automatically. People forward invites, print them, and read them on phones that show the wrong zone. The written line is the one everyone trusts.

Step 5: The Five Facts every external invite carries

Every external meeting event must answer five questions without anyone opening another email:

Fact	Example
Where	Video link and dial-in, or full address with parking note
Who	Names, roles and companies of all attendees
Why	One line purpose: "Review Q4 roof repair contract"
What to prepare	Link to the agenda or prep document
When, in every zone	"10:00 AM ET / 3:00 PM UK"

Step 6: Confirm, then brief

Confirmations: about 24 hours before every external meeting, send a short confirmation to the other side (see the Meeting Confirmation template). Log any no-shows and tell the client.

The evening brief: at the end of your shift, send the client a short brief for tomorrow:

Tomorrow, (DAY AND DATE), all times ET

9:00 to 9:25: Call with (CONTACT NAME), (COMPANY). Purpose: pricing review. Prep: proposal linked in invite.
11:00 to 12:00: In person at (ADDRESS). Leave by 10:20 (35 min drive).
2:00 to 2:50: Interview, (CANDIDATE NAME). Kit linked. Heads up: 1:00 to 2:00 is your only free hour. (CONTACT NAME) confirmed. (CONTACT NAME) has not confirmed yet; I will follow up at 8:00 AM.

Rescheduling and cancellations

If someone asks to move a meeting, offer two or three specific new times (with holds), never "when works for you?" alone.
Never move, decline or accept a VIP meeting without the client's approval.
Never delete an event the client created. If something looks wrong, add a note in the event and ask.
When a meeting is cancelled, free the time and tell the client in the next update.

Scheduling links

If the client uses a booking link, check its settings weekly: available hours match the rules, no weekend or late-night slots by accident, buffers and maximums switched on, the right time zone, and the right meeting link.

Never do this: never book anything that costs money (flights, hotels, event tickets, paid services) without the client's written approval of that exact option and price. Hold or reserve with free cancellation where possible, then confirm.

Never do this: never send an invite without checking the time zone line. One wrong zone can mean a missed investor meeting or an interview candidate waiting alone on a video call.

Common mistakes

Mistake	Fix
Booking in your own time zone	Calendar display set to the client's zone
Proposing times without holds	Hold every proposed slot immediately
Invite with only a link and no purpose	Five Facts, every time
Back-to-back meetings all day	Buffers and a daily maximum in the rules
Not checking the evening before	Evening brief, every shift

You proposed three times to a supplier yesterday and they have not replied. What do you do with the holds?
A meeting has attendees in New York, London and Sydney. What do you write in the invite?
Which weeks of the year need extra time zone checks, and why?
The client's VIP asks to cancel. The client is asleep. What do you do?
