All times are local clock times for one day. No dates or time zones are assigned. This CSV is a planning sheet, not a reservation or a Cowlendar import file.
Plan the time around the appointment.
A 30-minute session with a 10-minute buffer creates start times 40 minutes apart. Each appointment must finish before the break or closing time. The buffer separates sessions; no extra buffer is required after the last appointment in a working period.
floor((available minutes + buffer) ÷ (duration + buffer))
The schedule restarts at the end of your break. For 09:00–17:00 with a 12:00–13:00 break, 30-minute sessions and 10-minute buffers, the result is 10 slots.
From a draft schedule to live bookings.
- Use the generator to balance opening hours, preparation and breaks.
- Set capacity to match your staff, rooms or class seats.
- Download the CSV to share the plan with your team.
- Configure availability and buffers in your booking app so customers only see valid slots.
Good questions.
How do I generate 15-minute or 30-minute time slots?
Enter your opening and closing times, then set the appointment duration to 15 or 30 minutes. Set the buffer to zero for back-to-back appointments, or add preparation time between them.
Does the buffer apply before lunch or after closing?
The tool requires each appointment to finish inside its working period. A buffer is placed between appointments, with no extra buffer after the final appointment before a break or closing.
Can I use this for group classes or several staff members?
Yes, if every slot has the same capacity. Enter the number of bookable places. The tool multiplies slots by capacity; it does not model separate staff schedules or shared equipment conflicts.
Can I generate an overnight schedule?
This version plans one day, so closing time must be later than opening time. For overnight availability, generate the two daily working periods separately.
Can I import the CSV into Cowlendar?
The CSV is a simple schedule for planning and sharing. It does not reserve appointments or act as a supported Cowlendar import file. Configure your actual service availability in the app.
Are the times adjusted for daylight saving?
No. The generator creates local clock times without attaching a date or time zone. Use the time zone converter for date-specific international scheduling.
