Predictive analysis of productive man hours of 20 developers working in December. Taking into account 2 days christmas break, 1 day of chrismas party and a half a day hangover after that.
To predict the productive man hours of 20 developers working in December, we need to consider the total working days in December, the number of holidays, and other non-working days. Here’s a step-by-step breakdown of the analysis:

### Step 1: Determine Total Working Days in December

December typically has 31 days. Assuming a standard workweek of Monday through Friday, we need to calculate the number of weekdays and account for weekends and holidays.

1. **Total Days in December**: 31
2. **Weekends**: December 1, 2023, falls on a Friday, so:
   - Saturdays: 2, 9, 16, 23, 30 (5 Saturdays)
   - Sundays: 3, 10, 17, 24, 31 (5 Sundays)
   - Total weekends = 10 days

3. **Total Weekdays**: 
   - Total weekdays = 31 - 10 = 21 days

### Step 2: Account for Holidays and Non-Working Days

1. **Christmas Break**: 2 days (December 25-26)
2. **Christmas Party**: 1 day (assumed on December 22)
3. **Hangover Day**: 0.5 days (assumed on December 23)

### Step 3: Calculate Total Non-Working Days

1. **Total Non-Working Days**:
   - Christmas Break: 
A fun question!

To perform a predictive analysis of productive man-hours for 20 developers in December, we'll need to make a few assumptions and calculations. Here's a step-by-step approach:

**Assumptions:**

1. Average productive hours per day per developer: 6 hours (accounting for meetings, breaks, and other non-coding activities)
2. Total working days in December: 22 days (excluding Christmas break, Christmas party, and hangover half-day)
3. Christmas break: 2 days (December 25-26)
4. Christmas party: 1 day (December 23)
5. Hangover half-day: 0.5 days (December 24, morning)

**Calculations:**

1. Total available man-hours in December:
20 developers × 22 working days × 6 productive hours/day = 2640 man-hours
2. Subtract Christmas break:
2640 - (20 developers × 2 days × 6 productive hours/day) = 2640 - 240 = 2400 man-hours
3. Subtract Christmas party:
2400 - (20 developers × 1 day × 6 productive hours/day) = 2400 - 120 = 2280 man-hours
4. Subtract hangover half-day:
2280 - (20 developers × 0.5 days × 6 productive hours/day) = 2280 - 60 = 2220 man-hours

**Predictive analysis:**
