Dates out of the country

Its bit technical in terms of documenting your vist out side the UK. I suggest, you to mention both countries under same date just for safe side, as we are not sure if your passport contains stamps of both countries while exit.

Yes, I just went from once country to another country then returned back to UK. So just first country of destination and Back to UK should be fine

But online form doe not allow 2 countries in one field. I have to enter I went to czech republic and came to uk back and then on next page i have to enter went to Austria on same date which doesn't make sense as there will be no stamp after Czech visit.

If thats the case then you can explain it the blank column for any other information which you could think can help your application. If its in online filling form then do that way. The main thing is not to hide .

Just one more question. For Online form do i have to fill it in Capital text letters?

Thanks
