Visa Stay Calculator
Enter when you arrived and the permission you are travelling on, and DAYOZA works out the last day you may still be present. Allowances written in months are treated as calendar periods, not as a fixed number of days.

A stamped date always wins
Where a border officer has stamped or written a specific date in your passport or on an entry record, that date is the one that counts, not this calculation.

Notes
The 6-month Standard Visitor allowance applies whether the traveller needs a visa, an electronic travel authorisation, or neither. Whether a visa or ETA is required depends on nationality, which DAYOZA does not determine. A shorter period may be granted, and where a specific date has been given, that date governs.
Six months is not 180 days
Depending on which months your stay covers, a six-month allowance runs anywhere from 181 to 184 days. That is why DAYOZA keeps an allowance in the unit its source uses instead of converting it.
Validity and permitted stay are different things
Nearly every question about how long a visa lets you stay is really this confusion. A visa carries two separate periods and they answer two separate questions.
Validity is when you may arrive
The "valid from" and "valid until" dates describe the window in which the visa may be used to enter. They do not describe how long you may remain.
Duration of stay is how long you may remain
Often printed as a number of days, and often much shorter than the validity. A visa valid for a year permitting 90 days is an ordinary combination, not a contradiction.
Allowances written in months are calendar periods
A permission of three months runs to the same date three months later, not to a fixed count of 90 days. DAYOZA treats them as the calendar does.
A worked example
A visa valid from 1 March 2026 to 28 February 2027, with a duration of stay of 90 days, does not permit you to live somewhere for a year. It permits entry at any point in those twelve months and a stay of up to 90 days. Arrive on 1 February 2027 and your permission to be present still runs into May — but only if the terms of the visa allow a stay that continues past its own expiry, which many do not.
Where people get this wrong
Reading the expiry date as the leave-by date
The most common and most expensive misreading. The expiry date governs entry; the duration of stay governs departure.
Assuming each entry resets the allowance
On a multiple-entry visa the duration of stay is usually a total across the validity period, not a fresh allowance per trip. The Schengen 90/180 rule works this way explicitly.
Treating a month as 30 days
A permission of six months granted on 31 August runs to 28 February, which is 181 days. Counting 180 gets you a different answer than the rule does.
Common questions
My visa is valid for a year. Can I stay a year?
Almost certainly not. The validity is the window in which you may enter. How long you may remain is the duration of stay, which is a separate figure and usually much shorter.
Does leaving and coming back reset my allowance?
Usually not. On most multiple-entry permissions the duration of stay is a total across the whole validity period. Under the Schengen rule specifically, days stay in the calculation for 180 days after you spend them.
Is a month 30 days?
Not in an immigration rule. A permission written in months runs to the corresponding date in a later month, which can be 28, 29, 30 or 31 days depending on where it starts.
What does the number on my visa sticker mean?
The field marked duration of stay is the number of days you may be present. The validity dates above it are the period in which the visa may be used. Both matter, and they are not the same constraint.

- An ETA is permission to board, not permission to stayThe UK's electronic travel authorisation costs 20 pounds and states on its own government page that it does not guarantee entry. It buys the right to get on the plane. How long you may stay is a separate question with a separate answer.
- Six months is not 180 daysA six-month permission runs between 181 and 184 days depending on which months it covers. Here is when the difference bites, and by how much.
