Internally, the data has the format like [StartHour, StartMinute, StartAmOrPm, EndHour, EndMinute, EndAmOrPm] Now what happens say I want to add a flag to switch this data because I want to take the day off. Yes, I can clear the data. But I would still need an additional piece of data added to this format so when if I traverse of this list, the app knows to do whatever when it sees the "day off" flag. Likewise, what happens if I want to take a day off, and still get paid? Maybe I want to do this because I want to use some paid personal time (PTO) off before the end of the year. This is because my PTO might not carry over to the following year.
