I use Hebcal each year to set up the calendar for different schools I work with. This year, I am noticing that when I download the PDF of the calendar and check it against the calendar online, the candle lighting and Havdalah times start off the same in January, but begin to show some 1-minute discrepancies in April and May, increasing throughout June and July, reaching 3-minute discrepancies in August and September, then decreasing again from October through December. It seems like the PDF is being generated using a different set of parameters than the online version.
Has anyone else noticed this? Is this an existing issue with a known workaround or a new issue?
