According to the West Bengal School Holiday List , We, Teaching-Non-Teaching staff & Students, have been doing 53 min extra on daily basis since last 4 years
1 year = 365 days. Sunday + other Holidays = (52+65) days =117 days.
Total Working days= (365-117) days = 248 days.
For Exam =12 days.
So, the Teaching-Learning days =248-12=236.
Now, 236 days= 39.33 Weeks.(236/6
=39.33) (because Sundays are already deducted).
But in the List it is mentioned as 33.71 Weeks. (236/7=33.71)!!!
Per Week Class Scheduled = 31 hr.
Per Year Class= (31*33.71)hr=1045hr.
Actually Per Week Class =(1045/39.33)hr.=26 hr 35 min.
So, (31hr-26hr35min)= 4 hr 25 min extra working hour per week.
