Understanding the Work Days Until Summer Solstice Calculation

As we anticipate the celebration of Summer Solstice 2025, let's explore the method behind calculating the number of work days remaining.

The Formula

The calculation of work days until Summer Solstice uses the following formula:

Work Days = Total Days - (Weekends + Holidays)
Where:
- Total Days: The number of calendar days from today until Summer Solstice
- Weekends: The number of Saturdays and Sundays in this period
- Holidays: The number of federal holidays falling on weekdays in this period
                        

Calculation Steps

  1. Calculate the total number of days from today until Summer Solstice.
  2. Determine the number of weekend days (Saturdays and Sundays) in this period.
  3. Identify the number of federal holidays that fall on weekdays during this time.
  4. Subtract the weekend days and holidays from the total days.

Example Calculation

Let's walk through an example using hypothetical dates:

Given:
- Today's date: January 1, 2025- Summer Solstice date: June 20, 2025
Step 1: Calculate total days
Total Days = June 20 - January 1 = 171 days

Step 2: Determine weekend days
Weekends = 171 ÷ 7 × 2 ≈ 49 days

Step 3: Identify holidays (assuming 5 federal holidays in this period)
Holidays = 5 days

Step 4: Calculate work days
Work Days = Total Days - (Weekends + Holidays)
          = 171 - (49 + 5)
          = 171 - 54
          = 117 work days
