खैर इसको पीट-पीटकर मार डाला गया है। :) हालाँकि मैं अभी भी एक और उत्तर देने जा रहा हूँ क्योंकि मुझे कुछ अलग चाहिए था। यह समाधान इस मायने में अलग है कि यह एक बिजनेस टाइमस्पैन लौटाता है शुरुआत और अंत के बीच , और आप दिन के व्यापार घंटे निर्धारित कर सकते हैं, और छुट्टियां जोड़ सकते हैं। तो आप यह गणना करने के लिए उपयोग कर सकते हैं कि क्या यह एक दिन के भीतर, दिन भर में, सप्ताहांत में और यहाँ तक कि छुट्टियों के दौरान भी होता है। और आप केवल व्यावसायिक दिनों को प्राप्त कर सकते हैं या केवल प्राप्त किए गए टाइमफ़ैन ऑब्जेक्ट से आपको ज़रूरत नहीं है। और जिस तरह से यह दिनों की सूचियों का उपयोग करता है, आप देख सकते हैं कि गैर-कार्य दिवसों की सूची को जोड़ना कितना आसान होगा यदि यह विशिष्ट सत और सूर्य नहीं है। और मैंने एक साल तक परीक्षण किया, और यह सुपर फास्ट लगता है।
मुझे उम्मीद है कि कोड चिपकाना सटीक होगा। लेकिन मुझे पता है कि यह काम करता है।

और यहाँ परीक्षण कोड है: ध्यान दें कि आपको इस फ़ंक्शन को काम करने के लिए टेस्ट कोड के लिए डेटहेल्पर नामक कक्षा में रखना होगा ।
