Time Zone in WPF Scheduler (SfScheduler)
22 Jul 20217 minutes to read
WPF Scheduler allows to create appointments in various time zones and display them in the respective time zone or any other time zone. Use the time zone in the following four different ways:
- Create appointments in different time zones.
- Display appointments based on the client’s time zone.
- Display appointments based on scheduler time zone.
- Display appointments at the same time everywhere regardless of client’s time zone.
The following Time Zone’s respective countries are added to cover all the time zone regions. Use any of the time zones from the following list for scheduler time zone.

Create appointments in different time zones
Create appointments at different time zones using the StartTimeZone and EndTimeZone properties of ScheduleAppointment. An appointment’s start time and end time are calculated based on the given time zone information for the start time and end time. Set different time zones to the StartTimeZone and EndTimeZone properties.
Use the StartTime and EndTime properties of ScheduleAppointment to get the exact start time and end time of an appointment. By using the ActualStartTime and ActualEndTime properties, get the exact appointment rendering time.
var appointments = new ScheduleAppointmentCollection();
appointments.Add(new ScheduleAppointment()
{
Subject = "Meeting",
StartTime = DateTime.Now,
EndTime = DateTime.Now.AddHours(1),
StartTimeZone = "India Standard Time",
EndTimeZone = "India Standard Time"
});NOTE
- If the recurring appointment is converted to another time zone, then the whole sequence will be recalculated according to the new time zone information.
- If an all-day appointment is created, it’s start time and end time will be set to 12 A.M. and 12 A.M. by default, so time zone is not applicable for all-day appointments.
- Scheduler supports daylight saving time.
- The time zone support is applicable for custom appointments too, so map the corresponding property.
- Use TimeZone for custom appointments by mapping the StartTimeZone and EndTimeZone custom properties of AppointmentMapping.
Display Appointments based on client’s time zone
Display the appointments based on the client’s local time zone in scheduler. For example, consider a scenario that you are in North Carolina and you want to set up a meeting at 10 A.M. on North Carolina time. You have colleagues in London and Chennai, and they also need to participate. The time for this meeting will be 3 P.M. (15:00) in London and 5.30 A.M. in Chennai. When each view your Scheduler, you need to see the appointment displayed relative to your local time zones 5.30 A.M., 10 A.M., and 3 P.M., respectively. It can be achieved by setting schedule time zone to default (it will consider your device’s local time zone as schedule time zone) and appointment’s time zone to Eastern Standard Time (North Carolina) [as you are in North Carolina and it’s time zone is Eastern Standard Time].
Display appointments based on Scheduler time zone
Set the specific time zone to schedule using the TimeZone property of scheduler. On this scenario, the appointments will be displayed in UTC time when the StartTimeZone and EndTimeZone properties of ScheduleAppointment are set to null. The appointments will be displayed in UTC time based on the given scheduler time zone.
<syncfusion:SfScheduler x:Name="Schedule"
TimeZone="Central America Standard Time"/>this.Schedule.TimeZone = "Central America Standard Time";Display appointments at same time everywhere regardless of client’s time zone
Display the appointments at the same time everywhere without considering the time zone while setting the TimeZone property of the scheduler, the StartTimeZone and EndTimeZone properties of ScheduleAppointment to null. The appointments will be displayed based on the given StartTime and EndTime of appointment everywhere without considering the time zone.
Updating StartTime and EndTime after drag and drop appointment based on time zone.
After rescheduling an appointment using drag and drop, appointment’s start and end time value will be updated based on scheduler time zone and appointment’s time zone.
For an example, consider the local time zone is India Standard Time, if you drag an appointment from 9 AM and drop this on 1 PM and the scheduler’s TimeZone is not set and the appointment’s StartTimeZone and EndTimeZone has set as AUS Central Standard Time (Darwin) then appointment’s start time and end time value will be converted from Local time zone to appointment time zone and the appointment’s start time will be saved at 9 AM.
If you set scheduler’s TimeZone as AUS Central Standard Time (Darwin) and the appointment’s StartTimeZone and EndTimeZone as Central Standard Time (Mexico) then the appointment’s start time and end time value has converted from scheduler’s time zone to appointment time zone and the appointment’s start time will be saved at 3.30 AM of next day.
If you set scheduler’s TimeZone as AUS Central Standard Time (Darwin) and appointment’s time zone was not set then the appointment’s start time and end time value converted from scheduler time zone to UTC time zone and the appointment’s start time will be saved at 10.30 PM.
