Hiya mate,

I think you may have made a mistake from the article.

It says "first and second of shawwal"

Shawwal being the lunar month after Ramadan.

Shawwal 1 is likely Sunday (possibly Monday depending on interpretations on which locations will be sighting the moon). It is impossible for it to be Saturday.

So it'll be Sun/Mon or Mon/Tues for private firms (provided this article is correct).

Hope this helps.
