It is new type of leave in which user is able to select first or second half of day for desired leave. This type of leave spans only single day and there's no end date in it. So if user wants to take more than one half-day leave, they have to create multiple requests - one per each calendar day. Taking half-day leave reduces available vacation days quota by 0.5 (half a day).
To request half-day leave, you have to select date (1) and half of day (2). Option AM stands for first half of workday and PM stands for second half.
