If you are viewing your calendar in a timezone that is not your anchor timezone - e.g. you set up your working hours in the UK, but you are abroad on holiday in a different time zone - you may find that in some weeks your working times will move by one hour.

This is the effect of the fact that the application of daylight savings time (or summer time in the UK) does not happen at the same time in every country, and in some locations it never happens.

So as an example, if you had working times set up in the UK of 13:00 to 17:00 on a Monday, these would normally be shown as 08:00 to 12:00 in New York. However between early March (e.g. from 11th March in 2019) to the end of March the working times in New York would move to 09:00 to 13:00. They would then revert back to 08:00 to 12:00 from early April onwards. 

If you move to another country you can change your working hours to link to your new timezone so they don't change in your location.

The times clients see in your public profile and in their Client Dashboard will always update to their local time zone, so the times shown to clients may differ from what you see in your Therapist Dashboard.
