Hello KARAN

Thanks for reaching out and posting such an interesting comment. Yes, you can manually specify holidays using the NETWORKDAYS.INTL function to customize which days are considered weekends and also lets you include specific holidays.

In your case, the first and second arguments in the formula are for the start and end dates; you can use 11 3rd arguments to consider only Sunday as the weekend. In the 4th argument, you insert the specified holiday.

=NETWORKDAYS.INTL(startDate, endDate, weekend, holidays)

I have developed a formula for January by focusing on your specified weekends and holidays.

=NETWORKDAYS.INTL(B2, B3, 11, A6:A7)

Hopefully, the formula will help; good luck.
