On what day of the week were you born? Under September in your step by step example there should be a 4, not a 3. Thanks for pointing that out!

On what day of the week were you born? Under September in your step by step example there should be a 4, not a 3. Thanks for pointing that out! Thanks for pointing that out! We have corrected it. A question. How did you get the offsets for the leap years? How did you conjure up this pattern? Please explain. This helped me out tremendously. I kinda like the Zeller's Rule. It works for all dates in the Gregorian calendar. Sundays. The applet returns Sunday for me regardless of the input. But great article. I think there would be some inherent interest in this. We checked and the applet. We checked and the applet works for us, so not sure what the problem is. sorry! Applet input.

Decade offset. What is the decade offset for 2020,2030. and so on. Also plz could you explain how to calculate the decade offset?? The explanation of the hard way. In the explanation of the hard way it says that after dividing 2978 by 7 you get 425 weeks with 3 days left over. Can you explain how that works if 2978/7=425.428? Where are you getting three days? RE: The explanation of the hard way. Permalink Submitted by Anonymous (not verified) on 25 June, 2013 In reply to The explanation of the hard way by Anonymous (not verified) When working with remainders it is easy not to spot this. If you took the units away leaving you with 0.428, you would see that 0.428 is 3/7. When talking about remainders 3/7 becomes a remainder of 3. Hope I helped. A simple Expalnation.

As you said, you ignore leap years that fall on a century like 1900 or 2100 unless the century is divisible by 4 like 2000. Century years are leap years if they are divisible by 400. Permalink Submitted by Murli (not verified) on 26 August, 2016 In reply to 2100 a leap year? by Anonymous (not verified) So 1900 and 2100 are not leap years, whereas 2000 is. The divisible-by-4 rule only applies to non-century leap years. Says I was born on a Sunday! Says I was born on a Sunday! I wasn't. tell all the year codes. whats the year code of 1984 and how to know year codes for all the years? Century Offsets. Where do I find the century offsets for longer ranges? Is there a way to calculate it? Error?? Doesn't seem to work with 11 July 1968?? It gives wednesday when in reality it was a Thursday. Can anyone fact check me. Not an Error. Permalink Submitted by Razmooo (not verified) on 8 November, 2017 In reply to Error?? by Sami (not verified) Decade offset = 6. Plus the 8. Plus 2 for leap years. That's 16 so far. July offset is 5. 21 in total. Plus 11, that's 32. Divide by 7 gives you 4 remainder 4. Which is a Thursday :) Year offset. In the practice it says 5 for the year offset. Above on this page it says 6. What I'm doing wrong? I went on internet and picked up random date: 1957-05-23. I calculated by myself and I got Wednesday. But on this website I got Thursday I don't know why. I checked it few times and didn't saw the problem: 23+0+0+7+1=31=3. Please help. Birthday. Permalink Submitted by Ian L (not verified) on 24 February, 2018 In reply to What I'm doing wrong? by Someone (not verified) This method managed to get not just my own but all my children birth days wrong, also far to complicated in the decade - this way works! 30/05/1981 Year figure Divide 81 by 4 discard remainder and add to 81 e.g. 20+81 =101 Mod7 gives you 3 Month figure - use the (similar to the other method but. ) 033614625035 Therefore May=1 Day figure=30 Therefore 3+1+30 =34 Mod7 is 6 Saturday CORRECT!! Using their method you 30+0+3+0 which gave Mod 7 of 5 Friday, which is incorrect. number whrong.

Same issue. Permalink Submitted by Devan Phillis (not verified) on 14 August, 2018 In reply to What I'm doing wrong? by Someone (not verified) I used Jan. 24 1969, 24(day)+6(Jan)+6(1960)+9(1969)+2(leap year)= 47 47/7=6 r5 5 is Thursday, both calendar and applet say Friday. What am i missing? Monday is 1 Friday is 5. Permalink Submitted by Allan (not verified) on 4 April, 2019 In reply to Same issue by Devan Phillis (not verified) Monday is 1 Friday is 5. Decade offset for 2020? Thanks so much for this article, has been really helpful. Please can someone tell me what the decade offset is for 2020? Otherwise my superpower will become redundant!
