Carbon Difference for Humans

Technically, it's lacking a couple of hours till the complete period. You can work around that by adding ->endOfDay() into the chain.

If I do

Carbon::now()->addSecond()->endOfDay()->diffForHumans();

Carbon::now()->addSeconds(60)->endOfDay()->diffForHumans();

Both return "3 hours from now"

Yes, because in both cases you make the date to be the last second of the day and it's 3 hours before the end of the day now ;)

It's actually the same result. I have a date, need to add time to it and have the diffInHumans() come back with the right info.

If I add a year in this example, and it returns 11 months from now, that's not correct. I'm sure it's returning 11.9474 or something like that and it's rounding down/floor etc...

Should it round up?

I thought it was just taking the first unit of the diff

eg 11months, 30 days, 12 hours = 11 months

5 hours, 59 minutes = 5 hours

You can specify the number of parts you want if that helps... no sign of rounding though

Yes, you're right it takes from (11m 28d 23:59:59.491142). Yeah going to have to work with it some more to get what I need.

Also get tricky with leap year etc. Have to think more about what I'm doing and change things up.

...

I think the better solution is to make the human in to more parts to get more accurate.

->diffForHumans([ 'parts' => 2, ])

which will return "11 month 4 weeks from now"

See CarbonInterface::ROUND

$roundedDiff = $date2->diffForHumans($date1, [
    'parts' => 1, // Toon slechts 1 onderdeel (dag, uur, minuut, etc.)
    'options' => CarbonInterface::ROUND // Gebruik de afrondingsoptie
]);
