Conveying total time spent over years


I'm trying to say "I played a game for a TOTAL of 1880 hours or 78 days, over
a 5 year period."

I'm a 102 student and we aren't even through the first Genki book yet so this
is very hard for me to express with my current knowledge.

I found this and i think i can adapt it to work for me. [When is it
appropriate to choose にわたって or を通じて in regard to
time?](https://japanese.stackexchange.com/questions/6383/when-is-it-
appropriate-to-
choose-%e3%81%ab%e3%82%8f%e3%81%9f%e3%81%a3%e3%81%a6-or-%e3%82%92%e9%80%9a%e3%81%98%e3%81%a6-in-
regard-to-time)

> 試験のために、一年を通じて勉強した。
>
> 'I studied throughout the year without taking a holiday break (possibly for
> a few years) for the exam.'

Is this translation/adaption correct?

> 五年を通じて、ゲームを千八百八十時間か七十八日ぐらいしました。
>
> 'Over a 5 year period, I played a game for a TOTAL of around 1880 hours or
> 78 days.'




There is a word that native speakers frequently use but Japanese-learners
rarely, if ever, do to express the idea of " **cumulative total** " without
using a big Sino-loanword. That word is 「 **延{の}べ** 」.

You can say:

「５年間{ねんかん}で **延べにして** 1,880時間{じかん}（78日間{にちかん}）ゲームをした。」 ,

「５年間で **延べにして** 1,880時間（日数{にっすう}にして78日間）ゲームをした。」, etc.

If you want to sound a little more formal or technical by using a Sino-
loanword, you can replace the 「延べにして」 part by 「累計{るいけい}で」.

Note I did not use 「５年を通じて」 because it is not too natural-sounding.
