Dear Sudeepmalakr,
While putting "Mandays worked", we need to just put "No. of Present Days" during the Tenure. This has no link with "No. of Paid Days".
Days paid for W/off, Holidays, Leaves, etc. must be excluded (if not worked/Present).
In case of OT only 01 days will be considered.
Hope the above will resolve the query, seniors can share more inputs.
Rgds,
