GLM 5.2 vs GPT-5.6 Solfor everyday maths

**Estimate:**
Roughly **1,750 working hours** in a UK full-time year. 

**The 3 Assumptions:**
1. **Standard weekly hours:** The baseline work week is 37.5 hours (a common UK standard, sitting between the 35-hour weeks often seen in the public sector and the 40-hour weeks common in the private sector). 
2. **Paid time off:** The worker takes 28 days of paid leave per year. This is the UK statutory minimum (5.6 weeks), which typically includes the 8 public (bank) holidays. This leaves roughly 46.5 working weeks in the year.
3. **Sickness and abs…

**Rough estimate: about 1,740 working hours per year.**

Assumptions:

1. **37.5 paid working hours per week** (7.5 hours × 5 days).
2. **52 weeks per year.**
3. **28 days of paid leave**, including UK bank holidays—equivalent to 5.6 weeks.

Calculation:

\[
(52 - 5.6) \times 37.5 \approx 1,740 \text{ hours}
\]

The assumption that moves the answer most is **weekly contracted hours**. A 40-hour week under the same leave assumption gives about **1,856 hours**, whereas changing annual leave by one week changes the result by only **37.5 hours**.
