You can select a start and end date for your offer by entering a time and date in the Optional start date and Optional end date fields. If you don’t enter anything, your offer will activate as soon as you publish it and will remain active until you switch it off.
The app uses a 24-hour clock and is set to the timezone of the browser where the setting was added. For example, if you set your offer to end at 14:00 EST in Toronto, the offer would end at 11:00 PST in Vancouver.
