When only one country is closed: read the Reasons list
Overlap shows shared open days. Reasons names the holiday or weekend that blocked the other side — written for this tool’s calendar lists.

Answer: Open Reasons for your pair and month. Each one-sided day shows which calendar closed and the label from our holiday list or a weekend you left checked.
Tool: Compare working calendars — free, runs in this browser.
Shared open days answer “when can both teams meet?” Reasons answers the next question: “why is Thursday out?” Without that list you re-check both calendars by hand.
On this site a blocked day is either a weekend you still treat as closed, a date on the shipped holiday list for that country, or a custom closure you typed yourself. The Reasons page prints that label next to the date.
Use it before you argue about a “missing” meeting slot. If the label is wrong for your office, add or remove a custom date on Overlap and look again — the lists here are a planning aid, not a government gazette.
