Add business days to calculate realistic project and delivery dates excluding weekends and non-working days.
Calculate business days in India excluding weekends and national holidays with this free date calculator.
An Indian business date calculator counts working days between two dates, excluding Sundays, Saturdays (in 5-day work week environments), and major Indian national holidays like Republic Day, Independence Day, Gandhi Jayanti, and others.
Use it to calculate invoice due dates, project deadlines, and delivery windows in a way that is relevant to the Indian business calendar.
When payment terms say 30 business days, that is different from 30 calendar days. Using business days respects the actual working schedule and avoids asking for payment on a Sunday or a national holiday.
For project planning, delivery scheduling, and invoice due date setting, business day calculations are more realistic and professional.
Major national holidays like Republic Day (January 26), Independence Day (August 15), and Gandhi Jayanti (October 2) are fixed. Religious holidays like Holi, Diwali, and Eid vary by year.
This calculator accounts for major fixed national holidays. State-specific holidays may vary.
Enter a start date and an end date. The calculator counts working days excluding weekends and national holidays. You can also enter a start date and a number of business days to find the end date.
Use this for setting delivery dates, payment due dates, and project timelines.
If your invoice states 30 business days net payment terms, the due date calculated using business days may differ from a calendar day calculation by several weeks.
Always be explicit on your invoice about whether payment terms are in calendar days or business days.
