Step 2: Define Your Input Cells

Create named ranges for these critical inputs:

Input Type	Example Value	Cell Reference	Data Validation
Standard daily hours	7.5	Policy!B2	1-12, 0.1 increments
Standard weekly hours	37.5	Policy!B3	1-60, 0.1 increments
Core hours start	10:00 AM	Policy!B4	Time format
Core hours end	3:00 PM	Policy!B5	Time format
Flexi accrual rate	1.0	Policy!B6	0.5-2.0, 0.1 increments
Maximum balance	40 hours	Policy!B7	0-100, 0.1 increments

Step 3: Create Time Entry Log

Design a daily log with these columns:

• Date: Formatted as dd-mm-yyyy
• Day: Automatically populated (e.g., =TEXT(A2,”ddd”))
• Start Time: Time format with validation
• End Time: Time format with validation
• Break Duration: In hours (0.5, 1.0, etc.)
• Total Hours: Calculated as =End-Start-Break
• Core Hours Met: YES/NO based on policy
• Flexi Hours: Difference from standard day
• Running Balance: Cumulative total

Step 4: Implement Key Formulas

These Excel formulas are essential for accurate calculations:

Daily Flexi Hours:

=IF(AND(D2>=$B$4,E2<=$B$5),F2-$B$2,F2-$B$2)

Where:

• D2 = Start time
• E2 = End time
• F2 = Total hours worked
• $B$2 = Standard daily hours
• $B$4 = Core hours start
• $B$5 = Core hours end

Running Balance:

=IF(I2=””,0,IF(ROW()=2,I2,I2+I1))

Where:

• I2 = Current day’s flexi hours
• I1 = Previous day’s balance

Step 5: Add Visualizations

Create these charts to visualize flexi time patterns:

• Line Chart: Running balance over time
• Column Chart: Weekly flexi hours (positive/negative)
• Pie Chart: Breakdown of time usage
• Conditional Formatting: Highlight core hours compliance

Step 6: Add Data Validation

Implement these validation rules to prevent errors:

Cell Range	Validation Rule	Error Message
Start Time (C2:C100)	Time between 6:00 AM and 10:00 AM	“Start time must be between 6-10 AM”
End Time (D2:D100)	Time between 4:00 PM and 10:00 PM, after start time	“End time must be after start and between 4-10 PM”
Break Duration (E2:E100)	Decimal between 0.25 and 2.0 in 0.25 increments	“Break must be between 0.25-2.0 hours”
Flexi Hours (H2:H100)	Custom formula: =AND(H2>=-2,H2<=2)	“Flexi hours must be between -2 and +2”
