Why is scheduling so hard with ADHD?
Eight short chapters. Each one stands alone, so jump to the one you need.
Start here
After this chapter you will know what this guide covers and where to begin.
This guide is for people with attention deficit hyperactivity disorder (ADHD) who find it hard to book meetings. It is also for anyone whose mind works differently and who feels the same.
The team at Humble wrote it. Our team includes people with ADHD. Booking meetings is something we get wrong too.
Where do you want to start?
- I keep missing or double booking meetings Start with the common problems.
- I want to pick a booking tool Start with the tools, side by side.
- I use Google Calendar and want a free booking page Start with the six setup steps.
How to read the labels
- From researchA study, the NHS or a health body says this.
- People reportPeople with ADHD said this to researchers, in a survey or to us. It shows what people live with. It has not been tested.
- Idea to tryA practical idea. Research has not tested it for ADHD. Try it and keep what works.
- Not yet studiedWe found no research on this yet.

What makes booking a meeting hard?
After this chapter you will know why a small job like "find a time" takes so much out of you.
Short answer
Booking a meeting by email is many small steps. You have to hold each one in your head and remember to come back to it. ADHD makes both of those harder.
From researchWorking memory. This is the short-term space where your brain holds what you are using right now. In ADHD it is often smaller and less reliable. To agree a time, you hold their dates, your dates and your plans all at once. That is a lot for working memory.
From researchRemembering to do it later. Researchers call this prospective memory. It is how you remember to reply on Thursday, or to add the meeting to your calendar. People with ADHD often find this hard. The job waits in your inbox, and nothing reminds you.
From researchTime. Many people with ADHD find it hard to sense how long things take or how much time has passed. People often call this time blindness. A review of 27 studies found that children and teenagers with ADHD judged time less accurately than others (Zheng and others, 2020). Most of this research is about young people, not adults.
Put these together and you get a pattern. "When works for you?" feels like a small question. But each reply is a new job to hold and to remember.
Booking a meeting: by email, or with a booking link
By email
- You suggest three times.
- You wait. You forget to check.
- They say none of them work.
- You suggest three more.
- They pick one. You meant to add it.
- You forget to add it to your calendar.
6 steps you must remember
With a booking link
- You send your link.
- They pick a time. It goes into your calendar.
1 step for you
What goes wrong when you book meetings?
After this chapter you will know the common problems. You will also know that it is not just you.
Short answer
The problems are rarely about caring too little. They come from memory, time and energy.
Does this sound like you?
- The reply you never sentSomeone asked when you are free. You meant to reply. A week later the email is still there.
- Two meetings at onceYou said yes to a time by email. You did not add it to your calendar. Then you booked something else at the same time.
- No time between meetingsOne call ends at 11:00 and the next starts at 11:00. You have no time to switch, eat or think.
- Too many in one dayEach meeting looked fine on its own. Together they took all your energy for the day.
- A meeting in one hourSomeone booked a slot for today. You had planned to use that time to focus.
- "What was this meeting for?"The meeting starts. You cannot remember who they are or why you are talking.
People reportThese are the problems people with ADHD describe to us and in online groups. Each one links to a setting in the next chapter.
How does a booking link help?
After this chapter you will know which settings fix which problem.
Short answer
A booking link is a web page that shows the times you are free. People pick a time and it goes straight into your calendar. You set the rules once, and the page keeps them for you.
A booking link does more than save emails. Its settings let you protect your time and energy before anyone books. You make the choice once, on a good day. You do not have to make it again for each meeting.
Each problem, and the setting that helps
Idea to try- The reply you never sentThe link itself. People book without waiting for you.
- Two meetings at onceCalendar check. The page hides times when you are busy.
- No time between meetingsBuffer time. A gap of 15 minutes or more after each meeting.
- Too many in one dayDaily limit. For example, no more than 3 bookings a day.
- A meeting in one hourMinimum notice. For example, people must book at least 24 hours ahead.
- "What was this meeting for?"A booking question. Ask "What do you want to talk about?" The answer is saved in the meeting.

Which booking tool should I use?
After this chapter you will know which tool fits you, and what each one costs.
Short answer
If you use Google Calendar, start with its free appointment schedules. If you want more than one kind of meeting for free, try Cal.com or Zcal. If you do not want another monthly bill, look at TidyCal.
Every tool below can share your free times, check your calendar and add the meeting for you. They differ in what is free and in how many settings they show you. For many people with ADHD, fewer choices are easier.
| Tool | Free plan | Paid plan | Good for ADHD because | Watch out for |
|---|---|---|---|---|
| Google Calendar appointment schedules | One booking page. Buffers and a daily limit. | A paid Google plan adds more booking pages and email reminders. | It is part of the calendar you already use. There is no new app to remember. | No reminder emails on the free plan. |
| TidyCal | A small plan with one calendar. | Pay once (about $29) instead of every month. | No monthly bill to forget. Simple screens. | The free plan has a limit on bookings each month. |
| Cal.com | Free for one person. As many kinds of meeting as you want. | Paid plans are for teams. | All the settings in Chapter 04 are free. | It has a lot of settings. That can feel like too much at first. |
| Zcal | Free booking links, calendar checks and video links. | About $7 a month for extra team features. | Free, clean and calm to look at. Has polls for group meetings. | A smaller company, with fewer reviews. |
| Calendly | One kind of meeting and one calendar. | From about $10 a month. | Many people already know it, so you explain less. | The free plan is small. Most people end up paying. |
Prices are in US dollars and come from each company's pricing page or recent reviews, checked in October 2026. They change often, so check before you pay. Humble is not paid to name any of these tools.
Pick by what you need
- "I already live in Google Calendar." Use Google's appointment schedules. Chapter 06 shows how.
- "I forget to cancel subscriptions." TidyCal lets you pay once.
- "I need different meetings, like a 15 minute chat and a 1 hour call." Cal.com or Zcal give you this for free.
- "The people I meet all use Calendly." Calendly is fine. Its free plan works if you only need one kind of meeting.
How to set up a free booking page in Google Calendar
After this chapter you will have a booking link to send. It takes about 10 minutes.
Short answer
In Google Calendar on a computer, click Create, then Appointment schedule. Set your hours and rules, then save and copy the link.
You need a Google account and a computer. A free account gives you one booking page. That is enough for most people.
The small pictures are simple drawings. Google's own screens may look a little different.
-
1 Open a new appointment schedule
Open Google Calendar on a computer. At the top left, click Create. Then click Appointment schedule.
-
2 Give it a name and a length
Use a plain name, like "30 minute call". Pick how long each meeting is. Shorter meetings are easier to fit in a day.
-
3 Choose your bookable hours
Under General availability, set the hours people can book. Only offer the hours when you have energy for people. Leave your best focus time off.
-
4 Set your rules
Under Scheduling window, set how soon people can book. 24 hours means no surprise meetings today. Under Booked appointment settings, add Buffer time and Maximum bookings per day.
-
5 Add one question to the booking form
Click Next. Under Booking form, add a question: "What do you want to talk about?" Their answer is saved in the meeting, so you know why you are meeting.
-
6 Save and share your link
Click Save. Click the schedule in your calendar, then Share, and copy the link. Paste it into your email signature. Now you never have to look for it.
Idea to tryNo reminders on a free account. Google only sends reminder emails to people on a paid Google plan. So set your own: in your Google Calendar settings, add a default notification to your events. Google Calendar lets you choose how many minutes before.
Bookings go into your Google Calendar. If you connect Google Calendar to Humble, each meeting appears in your day, next to your tasks and notes. Filter your timeline by a person to see every meeting you have had with them. Then you can read your notes before you talk.
Common questions
Short answers to the things people ask most.
Is Google appointment scheduling free?
Yes. With a free Google account you get one booking page, and people can book as many meetings as you allow. A paid Google plan adds more booking pages and reminder emails.
What is the best free alternative to Calendly?
If you use Google Calendar, its appointment schedules are free and already in your calendar. If you want more than one kind of meeting for free, Cal.com and Zcal both allow that.
Is it rude to send a booking link?
Most people find it helpful. To keep it warm, add a line like "Here is my booking link. If none of the times work, just tell me." That gives them a choice.
What booking settings help most with ADHD?
Buffer time after each meeting, a daily limit, at least 24 hours' notice, and one question on the booking form. Chapter 04 explains each one.
Will a booking tool fix my time blindness?
No tool fixes it. A booking tool takes some of the remembering out of your head, so you have less to hold. Reminders and a calendar you look at every day do the rest.
