How do I avoid showing up too early or too late in professional settings when I have ADHD
Arriving too early or too late to meetings is a common experience for adults with ADHD. According to NICE guidance on ADHD (NG87) and NHS self-help materials, these patterns are not about motivation but reflect real differences in how ADHD affects time perception, planning, and executive control. Research shows that “time blindness” and fluctuating temporal awareness make it genuinely harder to estimate how long tasks take or to judge when to begin getting ready.
Understanding why ADHD affects punctuality
A 2023 review of time perception in adult ADHD found that adults with ADHD consistently misjudge time intervals, often leading to over- or underestimation. When a task feels short in the moment, it is easy to leave too late; when anxiety about lateness is strong, people may leave very early to avoid stress. This can create an unpredictable pattern of arrival times. The ADHD Evidence Project’s meta-analysis confirmed that timing and organisational difficulties are central to ADHD and are part of its neurological basis rather than poor habits.
Executive-function difficulties, such as problems with working memory and sequencing, make it hard to hold future intentions in mind. As a result, cues like “leave at 8:15” are easily lost amid distractions. UK self-help guidance notes that anticipatory anxiety about lateness can push people to over-compensate by leaving too soon, while on other days, low urgency leads to rushing or running late.
Practical workplace strategies
NHS and NICE-aligned resources recommend a combination of environmental tools and behavioural strategies. Using multiple phone alarms or visual timers helps make time visible instead of relying on internal awareness. NHS booklets advise setting two alarms, one for “start getting ready” and another for “leave now.” Structured approaches such as backward planning, where you work backwards from the arrival time (“meeting at 9:00 → travel 30 minutes → preparation 20 minutes → start at 8:10”), are also widely supported.
CBT-informed coaching can help manage thinking patterns linked to punctuality, such as “time optimism” or fear of being late. The Frontiers in Psychology workplace review found that combined behavioural and coaching approaches improve organisation, planning, and time awareness.
Under the Equality Act 2010, employers have a duty to provide reasonable adjustments for adults with ADHD, such as flexible start times or written meeting reminders. These align with NICE recommendations for environmental support and psychoeducation as part of holistic ADHD management.
Private assessment and review services such as ADHD Certify can also help adults access structured support, particularly when workplace difficulties are affecting confidence or wellbeing.
Key takeaway
If you find yourself swinging between arriving too early or too late, it’s not a failure of discipline but a reflection of how ADHD shapes your sense of time. By making time visible, building predictable routines, and seeking structured support, you can create steadier patterns that reduce stress and improve reliability in professional settings.
