Clara is designed to take in to account your availability when offering times for meetings, which also includes your travel.
Unavailable Dates
For dates that you want to Clara to ignore completely, you can add events to your calendar so that Clara will avoid them.
If you use Google Calendar, you can add an All Day Event titled "DNS" to the days you're unavailable or add a regular time-based block that spans your preferred meeting times. You can add any additional context to the title after the "DNS", for example: "DNS: Houston Conference" or "DNS: Vacation".
Please note: Clara will ignore any All Day Events that do not start with "DNS".
If you use Office 365, you can add a regular time-based block like the one below to the days you're unavailable.
Travel
At times, you may travel and want to take meetings while in another location. Clara is able to make internal updates to your preferred meeting times to adjust for different locations or availability. If it detects that you mention travel or vacation, it will ask you if you would like to change your preferences. You can either let it know you do not want to take meetings during a certain period or change your current preferences for the duration of your travel. It will note this internally and respect these preferences during the mentioned time frame.
