I only know the year, or the year and the month. What day should I enter?

Pick one rule and use it for every record. Something like: the first day of the month when you know the month, and 1 July, the middle of the year, when you only know the year. Avoid 1 January as a placeholder — a great many people really do visit that day, for hatsumōde, so a placeholder there becomes hard to tell apart from a genuine New Year visit. If what you know is a Japanese era year, choose a day that falls inside that era: Heisei 31 ran only to 30 April, so a later date in that year would put you outside it.

The capture date of my photo is earlier than the date written on the goshuin.

Suspect your conversion first. Misreading a Japanese era year by one is enough to push the written date past the capture date. If the conversion holds up, then either the clock on the phone or the camera was wrong, or the photo's date and time were edited afterwards. Check the photos taken either side on the same device: if they are all out by the same amount, it was the clock, and you can subtract that offset from the undated goshuin photos too.

Can I write an estimated date into a photo whose capture date is gone?

Your photos app will let you adjust the date and time, but we would not. A date you typed in looks exactly like a real capture date the next time you open the photo, and nothing in the photo says it was a guess. Leave the photo's own date and time alone, and keep the estimate, with its reasoning, on the record side.

Do photos taken by the person I travelled with help?

They do. Even on a day when you photographed nothing but the page, a companion's photo of the same shrine or temple gives you a candidate day. The catch is in the sending: depending on how the photo reaches you, the capture date may be stripped on the way, so the reliable move is to ask them to read the date off the original on their own device.

When should I go back over the dates I estimated?

There is no schedule for it; the moment to revisit one is when a new clue turns up. Opening the physical book, going back through photos with the person you travelled with, finding an old diary or a hotel receipt. If you marked the estimates and wrote down what each one rests on, pulling up exactly the records worth revisiting takes seconds.

When was this goshuin? Tracing a visit date the page never recorded

Look at the goshuin itself first. If you can read a Japanese-era date near the words 奉拝 (hōhai), that is the visit date. If you cannot, open the photograph of the goshuin in your photos app, read its capture date, and see whether photos of the grounds or of the journey sit either side of it from the same day — that usually narrows the candidates to a day or two. A capture date points at the day you visited or a later one, and a photo you were sent in a message often carries the day you saved it instead, so any date you cannot settle should be recorded as an estimate with the reason you chose it.

The key points of this article

Start with the goshuin itself: a date you can read on the page is the most reliable visit date there is
If the device clock was right, the capture date of a photo is the day you visited or a later day
Screenshots, and photos received in a message, often carry the day you saved them instead
The photos either side of the capture date, plus your travel records, narrow the candidates
Mark every date as confirmed, estimated or unknown, and write down what an estimate rests on

This article is part of “Goshuin photos piled up on your phone: how to organise them into a record afterwards”.

This article covers one thing only: how to trace a visit date afterwards when neither the book nor the photo recorded it. The format the date is written in, and how each shrine or temple handles the writing of one, are not the subject here.

Can you work out the visit date of a goshuin that carries no date?

Usually, if you put several clues together — though not always with certainty. Record the ones you settle as confirmed and the ones you do not in a form that reads as an estimate, and the question stops costing you time every time it comes back.

How reliable is each clue?

There are five, and the most reliable is a date written on the goshuin, then the pages either side of it in the book, then the capture date of your photo. Use the clues near the top of the table to fix a range, and the ones below to narrow it.

Clue	How reliable	Where to look
A date written on the goshuin	High. If you can read it, it is the visit date	Near the words 奉拝 (hōhai)
The pages either side in the book	High if you filled the book in order, but a span between two dates is left	The pages before and after in the same book
The capture date of the photo	Medium. The day you visited, or a later one	The info panel in your photos app
Photos either side from the same day	Medium. Good odds when shots of the grounds or the journey continue	Either side of the goshuin photo in your photos app
Travel and calendar records	Supporting. Produces candidate days, nothing more	Your calendar, transit card history, hotel booking emails

The pages either side are no use for a page you pasted a loose sheet onto later. None of the three clues from the capture date down can settle a date on its own, so use them together. Watch out in particular for a shrine or temple you have visited several times: it is easy to find a photo of its gate taken in a different year and tie the goshuin to the wrong visit. Keeping a goshuin from a repeat visit as its own record, and checking the earlier one against your notes, is a separate article.

Start with the goshuin itself

A visit date is written on the page more often than not. The usual layout puts the date, in a Japanese era, below or beside 奉拝 (hōhai) — "I have paid my respects."

Even when brushwork sits across it and will not resolve, enlarging the photo, or brightening just the part of it that holds the date, often makes it readable.

If you can read the date on the page, that is the most reliable visit date you have, and it comes before the capture date of any photo. The format itself is covered in "why the date on a goshuin is written in a Japanese era".

Four reasons the goshuin gives you no date

When there is no date to find, it is usually one of these four.

All you hold is a loose pre-written sheet. These are sometimes handed over with the date left blank, and then the goshuin itself can tell you nothing. Whether to write the date into that blank yourself is a decision that can wait until you have finished tracing the visit date.
The brushwork will not resolve. Writing over writing, or a seal crossing the characters.
The book is undated by design. In a nōkyōchō (納経帳) carried around a pilgrimage, the brushwork commonly leaves the visit date out, and what each pilgrimage or temple does is its own decision. Keeping the round and the day of a stacked seal outside the paper is covered separately.
Only the photo is left. The book is not to hand, and in the photo the date is cropped off or too blurred to read.

In every case you move on to the next clue.

Reading the capture date, and narrowing it with the photos either side

Open the photo of the goshuin, read its capture date and time, then page through the photos either side: that alone usually narrows the visit date to one or two candidates. The capture date and time is one of the values the camera writes inside the photo file, in a block called EXIF.

In the iPhone Photos app, look in this order. Screen names change between versions, so if something is not where we say it is, look for the nearest equivalent.

Open the photo of the goshuin in your library. If you can choose the sort order, sort by capture date rather than by the date added.
Swipe up on the photo, or tap the info button — the "i". The capture date and time appear, along with the place and the camera model when those were recorded.
Keep the photo open and swipe left and right through the photos either side. If shots of the gate, the grounds and the journey from the same day continue in both directions, that day is your first candidate. If the goshuin photo sits alone, days away from anything else, suspect that you photographed a batch of pages later, and go back further to look for photos taken near the shrine or temple.
If the place was recorded, compare it with the photos either side. A goshuin photo taken near your own home was probably taken after you got back.

A capture date is not the visit date

The capture date is where you start, not the answer.

It comes apart in cases like these:

You photographed nothing on the day, and shot the page on your desk once you were home
You let a few loose sheets pile up and photographed them together
The goshuin arrived by post and you photographed it the day it came

In all three the capture date is the later one. As long as the clock was right and nobody edited the date afterwards, a capture date cannot fall before the visit. Treat it as an upper bound on the visit date, never a lower one.

Photos whose date is not the day they were taken

The date your photos app shows is not always the day the photo was taken. Check these before you take one at face value.

Screenshots, and photos re-saved out of another app. The date can become the day it was saved.
Photos received in a message or from social media. The capture date and time can be stripped in transit, leaving the photo filed under the day you saved it.
Photos whose date you adjusted in the photos app. The date and time can be set by hand, and if they were, they are not the original.

A photo whose info panel shows no camera model may have lost its capture information altogether. If one day holds photos from scattered places and different seasons, suspect that the day is the day you saved them. For photos like these, the reliable answer is to check on the device that still holds the original.

When you visited several places in one day

The order you went round in comes out of the capture times of the photos that are not of goshuin. If the goshuin went into the same book one after another, page order is usually visiting order — but a loose sheet in the middle takes that away too.

The gate, the grounds, the view along the way, lunch: all of them carry a time, so lining the times up per shrine or temple gives you the order you went round in. The times on goshuin photos shot after you got home have nothing to do with it.

When you truly cannot tell, record it as an estimate

Do not leave a date you could not settle as an unmarked blank. An unmarked blank cannot say whether you have not looked yet or looked and failed, so the next time you open the record you do the same work again.

Use three marks: confirmed (checked against the date on the goshuin), estimated (taken from a capture date, the photos either side, or a year or a season) and unknown (no clue found). For an estimate, enter a representative date inside the range you do know, and write down what it rests on — something like "estimated (capture date; photos of the grounds either side)". When a firmer clue turns up, you can correct it without repeating the search.

If you keep your list in a spreadsheet, keep those three marks in a column of their own rather than mixed into a notes field, so you can filter down to the estimated rows. Putting a "how sure is this date" column in the sheet is covered in the article on choosing the columns.

In the app we make

In Goshuin Ledger, the app we make, importing a photo fills the visit date in from its capture date, and a photo that has no capture date gets the day you imported it instead. Which of the two you are looking at is shown per photo, so a photo whose capture information is gone can be spotted there. What the app reads is the date and time written inside the photo, so a photo re-saved with a new timestamp will show that day as its capture date.

Pick several photos at once from your photo library and they all arrive in Imported photos with that starting value, and you correct the visit dates before adding them to a book and its pages. The steps from a bulk selection to photos sitting on a book's pages are set out in order in a separate article.

Visit dates can be corrected photo by photo, or for a whole selection at once. Importing, and correcting the visit date, need no purchase.
Notes are searchable too. Searching for "estimated" brings back the records where you wrote it, newest visit date first, each with the book and the page it sits on.

A visit date is held as a single day, so a span like "sometime in spring" cannot go in as it stands, and there is no dedicated field for choosing between confirmed and estimated.

The first book needs no purchase and takes as many records as you like, and adding imported photos to a book one at a time needs none either. A second book and beyond, and adding two or more photos to a book at once, come with the one-time Ledger Full purchase; the range it covers is set out in the pricing section, and the App Store shows the current price.

One piece of sequencing to finish with: clear the goshuin whose visit dates you do know first, and deal with the unknown ones together at the end. The whole procedure is in "how to organise the goshuin photos piled up on your phone and turn them into records".
