A guest spot often comes down to a single hour. You set 2:00 PM from Paris, your client reads something else on their phone, and someone shows up at the wrong time. The problem is almost never the date: it's the question "2:00 PM — but where?"
The one rule that prevents every mistake
A tattoo happens in a specific city. So the appointment time is that city's time — not your phone's, and not your client's. Put another way: 2:00 PM in Tokyo stays 2:00 PM in Tokyo, wherever you look at your calendar from.
An appointment time without a city is only half the information.
Case 1 — You live in Paris and tattoo for a week in Tokyo
You plan your guest spot from Paris, a month ahead. You offer "Tuesday 2:00 PM" to a Japanese client. If your tool reads that time with your computer's clock, it saves 2:00 PM Paris time — that's 10:00 or 11:00 PM in Tokyo, depending on the season. Your client turns up in the afternoon; you're expecting them at night.
In Inkkore, your Tokyo stop has its own time zone, which you confirm once when you add it to your tour. For every day of the stop, the appointment's place is set to Tokyo, and the app shows "Local time of the tattoo · Tokyo" under the times. You type 2:00 PM: it's 2:00 PM in Tokyo, even if you're still in Paris.
Case 2 — Your client books a New York appointment from London
Many tools convert the time into the client's time zone. For a video call, that's handy. For a tattoo, it's a trap: your client reads 7:00 PM on their London screen, and that's the number they may still have in mind once they're in New York.
Inkkore does the opposite: it shows them the local time of the place, with the city written next to it — "2:00 PM · New York time" — on their page, in the confirmation email and in the reminder the day before. If they add the appointment to their Google, Outlook or Apple calendar, the exact moment goes in: their phone will convert it on its own while they travel.
Case 3 — You tattoo in several cities
Lisbon in March, Berlin in April, home the rest of the time. Each stop on your tour has its own time zone, and each appointment keeps its city's.
- Your calendar places each session at its city's time. When a week mixes several time zones, it says so above the grid, and each session shows its city.
- If two stops overlap on a day, the app asks you where you'll be — it never decides for you.
- Changing an appointment's place? The times stay the same (09:00–11:00) and become those of the new place. Nothing moves until you confirm, and Inkkore checks that no other session falls at the same moment.
- Changing your default city moves no appointment that's already booked.
Clock changes, without thinking about them
Twice a year, an hour disappears or repeats. A time that doesn't exist that day is refused; a time that happens twice makes you say which one. And an appointment booked in October for November stays at the right local time after the change.
What you actually have to do
- Confirm your city and its time zone once: Inkkore asks for it as long as it's missing.
- For each guest spot, set its time zone when you add the stop. Inkkore suggests one when the city name exactly matches a time zone, like Tokyo — check it, then confirm it.
- Then enter your times the way you'd tell your client: those of the city where you tattoo.
That's it. Your clients get the time they need to walk through the door, with the city's name, in their language.
