You sent the link. They booked a slot. Then someone showed up an hour early — or not at all. Calendly showing the wrong time is one of the most quietly frustrating problems in remote work, and it has four distinct causes, each with a different fix.

Why Calendly Shows the Wrong Time

Calendly displays times based on the timezone detected for the person viewing the booking page — not your timezone. If anything in that detection chain is off, the times shift.

1. Your Calendly account timezone is set incorrectly. This is the most common root cause. If your account is set to the wrong timezone, every event you create will be anchored to the wrong offset. Go to Account Settings → My Profile → Timezone and verify it matches where you actually are.

2. The invitee's device or browser timezone is wrong. Calendly reads the timezone from the invitee's device clock. If their laptop is set to the wrong city — a common issue after travel or a system update — Calendly inherits that error. They'll see times that are off by exactly the difference between their device timezone and their real location.

3. Daylight Saving Time transitions. If you set up a recurring event just before a DST change, the times can shift on the day clocks move. Calendly adjusts for DST, but if the event was anchored to a fixed UTC offset rather than a named timezone, it won't update correctly.

4. Timezone display setting on the booking page. Calendly has a setting that controls whether the booking page shows times in your timezone, the invitee's timezone, or lets the invitee switch. If this is set to your timezone by default and your invitee doesn't notice, they'll book in your local time without realising.

How to Fix It: Step by Step

Fix 1: Correct your account timezone. Log into Calendly. Go to Account Settings → My Profile. Find the Timezone field. Set it to your actual current timezone (not just your home city — check if you're currently in a different location). Save. All future events will now be anchored to this timezone.

Fix 2: Check your event type timezone settings. Open the event type that's showing the wrong time. Go to Edit → Date & Time. Look for Timezone settings — confirm it matches your profile. If you see a fixed UTC offset instead of a named timezone, change it to a named zone (e.g. "Europe/London" not "UTC+0") so DST is handled automatically.

Fix 3: Tell invitees to check their device clock. If an invitee is consistently seeing wrong times, ask them to check their system timezone in Settings (not just the clock — the actual timezone setting), verify it matches their physical location, and hard-refresh the Calendly booking page after correcting it.

Fix 4: Enable timezone display on your booking page. Open your event type. Go to Edit → Appearance (or Booking Page Settings). Enable "Display timezone" so invitees can see what timezone the times are shown in. Consider enabling "Allow invitees to change timezone" so they can self-correct.

The Deeper Problem Calendly Can't Fix

Calendly's timezone handling is generally reliable when both sides have accurate device settings and named timezones. The failure mode isn't really a Calendly bug — it's the fundamental friction of asking two people in different places to agree on a time using a link that requires one of them to leave their current conversation and interpret a calendar page.

The wrong time problem is a symptom of a workflow that separates the scheduling tool from the conversation where scheduling actually happens. Most scheduling still starts in chat — WhatsApp, iMessage, Telegram — where someone says "are you free Thursday?" The Calendly link is a workaround for the fact that there's no native scheduling layer inside those apps. When it works, it's fine. When it shows the wrong time, nobody knows whose fault it is.

A Different Approach

Wenya is a scheduling keyboard that lives inside WhatsApp, iMessage, and Telegram. Instead of sending a link out of the conversation, you send a scheduling proposal directly in the thread — one that shows each person their own local time, automatically adjusted for their timezone. No booking page. No timezone detection errors. No "wait, is that your time or my time?"
