Questions
Why leave out the first day?
Most rules count a period from the next day, so 30 days from 1 March ends on 31 March. Untick the box to count the first day too; the end date moves one day earlier.
Does it know public holidays?
No. It flags Saturdays and Sundays only. Check the holiday list that applies to you.
Is what I type sent anywhere?
No. It's worked out in your browser. Nothing you type leaves your device.
