Passport rules are counted from the wrong end of the trip
Validity, blank pages and permitted days are all measured against dates and quantities that travellers routinely misread, and the checks happen before you reach any border.

Validity is measured against your departure, not your arrival
The commonest passport mistake is arithmetic. People check that the document is valid on the day they fly out and do not check what the destination requires relative to the day they intend to leave it, which is the date that most rules are written against.
A country requiring a period of remaining validity is generally requiring it as measured from the date you exit, or in some formulations from the date of entry plus the length of stay. The distinction only matters when you are close to the threshold, which is exactly when people get caught.
The safe habit is to work backwards from the last day of the trip and add the required margin to that. If the answer is uncomfortably close, renew, because the alternative is being told at a check-in desk rather than at a border.
The six-month rule is a convention rather than a law
A great many countries ask for six months of remaining validity, which has led travellers to treat six months as a universal rule. It is not. Some require three months beyond the intended stay, some require only that the passport be valid for the duration of the visit, and a few impose additional conditions of their own.
The requirements also differ by nationality and by the type of permission you hold. Agreements between particular countries frequently relax the general rule for their citizens, which is why two people in the same queue can face genuinely different requirements with the same passport expiry date.
Because it varies this way, the only reliable source is the entry requirements published by the destination for your specific nationality. Third-party summaries are useful for knowing that a rule exists and unreliable for its current form.
Blank pages are a requirement, not a formality
Countries that stamp on entry and exit need somewhere to put the stamp, and a number of them specify a minimum number of entirely blank pages. Visas are worse, since a full-page visa consumes a page on its own and some missions will not issue into a passport without spare capacity.
Pages marked for endorsements or amendments usually do not count towards the requirement, which surprises people who look at a passport with space in it and assume they are fine. The requirement is normally for pages designated for visas specifically.
Where a passport is filling up, the practical answer is early replacement rather than optimism. Some countries permit additional pages to be added and many no longer do, so the availability of that option depends entirely on who issued the document.
The airline enforces the rules on behalf of the country
The check that actually stops people happens at check-in rather than at a border. Carriers are liable for returning passengers who are refused entry, and that liability is why a ground agent will decline to board someone whose documents do not satisfy the destination requirements as the carrier understands them.
This produces a particular frustration: the person refusing you is not the authority making the rule, cannot exercise discretion over it, and is working from a commercial database of entry requirements. Arguing the underlying law at a desk is not a route to boarding.
It also means the standard applied is sometimes stricter than the border would have been, because a carrier facing a fine has every reason to be cautious. The way to avoid meeting that caution is to satisfy the requirement with margin rather than exactly.
Permitted days are counted by rules that are easy to misread
Where a permission allows a number of days, how those days are counted is a separate question from how many there are. Entry and exit days commonly both count as full days regardless of the hour, which quietly removes a day from most calculations people make.
Rolling windows are the harder case. Some arrangements allow a number of days within a moving period rather than per visit, so each day you were previously present continues to consume your allowance until it falls out of the window. Working out the position on a given date requires looking backwards, not forwards.
Overstaying is treated as a serious matter in most jurisdictions and the consequences can extend well beyond the trip in question, including bars on future entry. Where a calculation is anywhere near a limit, that is the point to check the official rules and, if it is genuinely unclear, to get proper advice rather than to guess.
Common questions
Does a renewed passport carry over the visas in the old one?
Generally not automatically, and practice differs. Some countries allow you to travel with both documents so that a valid visa in an expired passport can still be used; others require the visa to be transferred or reissued. It depends on the issuing country of the visa, so check before renewing if you hold one.
Is a damaged passport a problem if it is still valid?
It can be. Passports with water damage, a detached cover or an unreadable machine-readable zone are refused with some regularity, because the document has to be verifiable by machine. The threshold is a judgement call made by an official, which is precisely why it is not worth testing.
Do the names on my ticket and passport need to match exactly?
They need to match closely enough that the carrier is satisfied you are the same person, and airline systems are less flexible than people are. Middle names, hyphenation and transliteration cause most of the trouble, and a mismatch is far easier to correct at the time of booking than on the day.
