Holiday Overlap
About Holiday Overlap
Holiday Overlap was built to solve a problem that anyone who has ever worked across borders or planned international travel has run into: not knowing when the other country is off work. A meeting gets scheduled on a national holiday nobody mentioned. A trip lands on a day when everything is closed. A project deadline falls on a day half the team isn't working.
The information to avoid all of this exists — it's just scattered across dozens of government websites, Wikipedia pages, and HR spreadsheets. Holiday Overlap pulls it into one place and makes comparison instant.
Our Mission
To help individuals and organizations save time, avoid scheduling conflicts, and make smarter plans by providing accurate, easy-to-use holiday comparison data for over 100 countries.
We believe that understanding each other's calendars is a small but meaningful step toward working better across cultures and borders. When you know that your colleague in Tokyo is celebrating a national holiday while you're filing a deadline request, you plan differently — and more considerately.
Who Maintains Holiday Overlap
Holiday Overlap is researched, edited, and maintained by the Holiday Overlap Editorial Team. The team reviews country-pair pages, planning guides, and data-source changes with a focus on practical accuracy for travelers, remote teams, HR teams, and international operators.
How the Tool Works
Holiday Overlap compares public, bank, and federal holidays between any two countries for any year from one year in the past to five years ahead. Holiday data is primarily sourced from the Nager.Date open-source holiday database and supplemented with official government calendar references where available.
When you select two countries and a year, we align every national public holiday in both calendars and surface the dates that fall on the same day in both countries — highlighting them so you can spot them at a glance. We focus on nationally observed holidays that apply across the whole country. Where regional variation exists, we note it.
What We Include
We include three categories of official days off:
- Public holidays — government-mandated days recognized nationwide, when most businesses and schools close.
- Bank holidays — days when financial institutions are legally required to close, often interchangeable with public holidays in countries like the UK and Ireland.
- Federal holidays — days observed specifically by federal government employees, as in the United States system.
Data Accuracy
We update our holiday data annually and rely on the Nager.Date project, which is one of the most widely used open-source holiday databases available. That said, holiday dates can change by government decree, and observance rules vary. For decisions with legal, financial, payroll, contractual, or travel implications, always verify dates with the relevant country's official government sources.
Who Uses Holiday Overlap
Travelers use the tool to check whether their destination country has a public holiday during their visit — so they know whether attractions will be closed, transport will be disrupted, or the city will be unusually busy. Remote workers and global teams use it to build overlapping holiday calendars and avoid scheduling meetings or deadlines on days when colleagues in other countries are off. HR and operations managers use it to plan annual leave policies, payroll cycles, and project timelines across multi-country teams.
