Sandwich leave policy

Sir, I want to know about the rule that will be followed in the case if an employee take leaves as per the situation given under: 1. We had Diwali Break from 24.10. 2019 to 10.11.2019 & Gurunanak Jayanti on 12.11.2019. 2. An employee was present on 23.10.2019 and then after leaves begin. 3. He remained absent on 11.11.2019 i.e. just after the completion of vacation period or on his first working date. 4. But immediately after that it is another holiday on 12.11.2019 and he will join on 13.11.2019. 5. In other words he remains on leave from 24.10.2019 to 12.11.2019 (Took leave in between two holidays) 6. Irrespective of his no. of leaves available and type of leaves , I want to know how the leave calculation will be done in this case?? If we follow sandwich rule then too he was present on the day before vacations and on the day after completion of 2 holidays. Please let me know what is to be done in this case as per the Central Government leaves and holiday rules. Thanks in Advance.
