Features

20+ country holiday calendars, add/subtract mode, and custom holidays

Most business day calculators only skip weekends. This calculator skips weekends and public holidays for 20+ countries. It covers the two most common use cases: counting working days between dates, and finding what date falls exactly N business days from now.

Days between dates

Count business days between any two dates. Shows total days, weekend days and holidays skipped. Lists every holiday that falls in the period. Include or exclude start/end date.

Add / subtract business days

Find the date that is exactly N business days from any start date. Works forward and backward. Essential for contract deadlines, delivery windows, SLA responses and payment terms.

20+ country holiday calendars

Public holiday data for UAE, Saudi Arabia, India, UK, USA, Australia, Canada, Germany, France, Singapore, South Africa, Nigeria and more. Updated for 2025 and 2026.

Custom holiday input

Add any extra dates to exclude on top of the country calendar. One date per line in YYYY-MM-DD format. Useful for company-specific shut-down days not in the national calendar.

Holiday breakdown

When counting between dates, every public holiday that falls in the period is listed by name and date so you can see exactly which days were excluded.

No weekend-only tools

A Saturday-to-Sunday skip alone is not enough for real business calculations. Including public holidays is what makes a business day calculator actually useful for contracts and deadlines.

Complete guide

Business Days Calculator — Working Days, Public Holidays and Deadlines

A business day is any day that is not a weekend (Saturday or Sunday) and not a public holiday. The definition varies by country: in the UAE, the working week runs Sunday to Thursday with Friday and Saturday as the weekend. In the Middle East more broadly, Friday is the Islamic holy day and is a universal day off. In Western countries, Saturday and Sunday are the standard weekend days. This calculator handles all standard weekend configurations and applies the correct public holiday calendar for each country.

Business days calculator with public holidays free

Public holidays significantly affect business day calculations, especially over quarter-end periods, festive seasons and long weekends. A calculation that only skips weekends will overcount working days when bank holidays, national days and religious holidays fall within the range. This calculator applies an up-to-date public holiday database for 20+ countries covering 2025 and 2026, and shows you every holiday it excluded by name so the calculation is fully transparent.

How many working days between two dates

To count working days between two dates: enter the start and end dates, choose your country, and click Calculate. The result shows the number of business days, the total calendar days, the weekend days excluded, and the public holidays excluded. You can choose whether to include or exclude the start and end dates themselves — different contexts use different conventions (some contracts count from the day after the triggering event, others from the same day).

30 business days from today calculator

The Add/Subtract mode finds the date that is exactly N business days from any starting point. Enter today's date (or click Set today), enter the number of business days, choose whether to go forward or backward, and click Calculate. The result is the target date. This is the essential calculation for: contract payment deadlines (often 30 or 60 business days), delivery estimates, notice periods, SLA response windows, T+2 financial settlement, and customs and immigration processing times.

UAE working days calculator

The UAE switched its weekend from Thursday-Friday to Saturday-Sunday in January 2022, aligning with the global business week. Government entities use a four-and-a-half-day week (Monday to Friday midday). Private sector companies largely operate Monday to Friday. UAE public holidays include New Year's Day, Eid Al Fitr (3 days, dates vary by moon sighting), Eid Al Adha (3 days), Arafat Day, Islamic New Year, Prophet's Birthday, Commemoration Day (30 November) and UAE National Day (2–3 December). The UAE calendar in this tool uses fixed Gregorian dates for secular holidays and accurate approximate dates for Islamic holidays based on the Hijri calendar.

Business day calculator excluding holidays India

India has a complex public holiday structure with three categories: national holidays (Republic Day 26 Jan, Independence Day 15 Aug, Gandhi Jayanti 2 Oct), restricted holidays (optional, from a list of 26 dates), and state-specific holidays (which vary by state). Most businesses observe the three national holidays plus major festivals. The India calendar in this tool covers the major national and widely observed festival holidays: Holi, Ram Navami, Eid Al Fitr, Eid Al Adha, Independence Day, Dussehra, Diwali, Christmas and the three national holidays.

Frequently asked questions

What counts as a business day?▼

A business day is typically any weekday (Monday to Friday in most countries, Sunday to Thursday in UAE and some Middle Eastern countries) that is not a public holiday. Banks, courts and financial contracts often have a specific legal definition of business day in the applicable jurisdiction. This calculator uses Monday-Friday as the default business week except for countries with different working week structures, and applies the public holiday calendar of the selected country.

Does the UAE use a different working week?▼

Yes. The UAE changed its working week from Sunday-Thursday to Monday-Friday in January 2022. The UAE now uses Saturday-Sunday as the weekend, aligning with most of the world. However, government entities work a four-and-a-half day week (Monday to Friday midday). Saudi Arabia, Kuwait, Bahrain and Qatar still use Sunday-Thursday as the working week with Friday-Saturday as the weekend. This calculator applies the correct weekend configuration for each country.

What is T+2 settlement and how do I calculate it?▼

T+2 (trade date plus two business days) is the standard settlement period for most stock market transactions in the US, UK, EU and many other markets. If you execute a stock trade on Monday, T+2 settlement means the trade settles on Wednesday (skipping no weekends). If the trade is on Thursday, T+2 is Monday (skipping the weekend). Use Add/Subtract mode with 2 business days forward from the trade date to calculate the settlement date. Note that some markets have moved to T+1 settlement.

How are Islamic holidays calculated?▼

Islamic holidays are based on the Hijri (lunar) calendar, which shifts approximately 11 days earlier each Gregorian year. This means Eid Al Fitr, Eid Al Adha and other Islamic holidays fall on different Gregorian dates each year. The dates are also subject to moon sighting confirmation and can shift by one or two days from astronomical predictions. This tool uses the officially announced approximate Gregorian dates for 2025 and 2026. For official UAE, Saudi Arabia or other government holiday dates, always verify against the respective government's official announcements, which are typically confirmed closer to the date.

Why does my result differ from another calculator?▼

Differences in business day results between calculators typically come from: (1) whether the start and/or end date is included in the count, (2) which public holidays are included in the database and whether they are accurate for the relevant year, (3) whether the calculator correctly handles the weekend configuration for the country (UAE Saturday-Sunday vs Saudi Arabia Friday-Saturday), and (4) whether substitute holidays (when a holiday falls on a weekend, the following Monday is often a substitute holiday) are included. This calculator lists every holiday it excludes so you can verify the calculation.

How do I calculate business days in a contract?▼

Contract business day calculations depend on the governing law of the contract. Most contracts start counting from the day after the triggering event (not including the trigger date itself). For example, if a payment is due within 30 business days of invoice date, and the invoice is dated 1 January, you start counting from 2 January. Use Add/Subtract mode with the day after the trigger date as the start date. For contracts governed by English law, the Law of Property Act definition of business day (any day other than Saturday, Sunday and Bank Holidays in England and Wales) applies unless the contract specifies otherwise.

What is the difference between calendar days and business days?▼

Calendar days count every day including weekends and holidays. Business days count only working days, excluding weekends and public holidays. If a contract says 30 calendar days, you count every day from the start date including weekends. If it says 30 business days, you skip weekends and public holidays, which typically adds 6-10 extra calendar days. 30 business days is roughly 6 weeks of calendar time in a jurisdiction with a standard Monday-Friday working week and typical public holiday density. Always check whether a contract specifies business days or calendar days, as the difference can be significant.

How many business days are there in a year?▼

In a standard year with a Monday-Friday working week, there are 261 weekdays (52 weeks times 5 days, plus 1 extra day). After subtracting public holidays, the typical count is: USA approximately 251 business days, UK approximately 253, Australia approximately 250, India approximately 250, UAE approximately 249, Saudi Arabia approximately 247. Leap years add one extra calendar day which may or may not be a weekday. The exact number varies by year depending on which day of the week the year starts and how public holidays fall.
