As you work, you'll likely use up your annual leave, but after using up a lot of it, you might wonder how many days of annual leave you have left for the year. In this case, enter the Base Date and the Maximum Days of annual leave you can use in this app, then mark the days of annual leave you've used or will use on the calendar each month. It will automatically calculate your remaining annual leave days. You can also manually designate full-day leave, half-day leave, half-day leave, and public holidays. When marking your leave, tap (click) on the date on the calendar to cycle through the following order: full-day leave -> half-day leave -> half-day leave -> public holidays -> default.
