How do I write Hebrew year 5005? 5000? 1005? 1000? 5? in Hebrew letters. What's the general rule?
general rule is without any preface, it is assumed that you are talking about this millenium. if you need to refer to a different millenium, you would preface the year with an aleph - daled for 1-4....
so while this year is technically ה' תשׁע"ט most people just write תשׁע"ט but if you were referring to the year 4321 you would write ד' שׁכ"א
