Calendar Display and Navigation

Kaluach can organize the calendar by either the civil month or the Hebrew month while keeping the same dates, holidays, events, and selection behavior.

Civil Month

Civil Month organizes the grid by the Gregorian month. It always runs left to right, from Sunday through Saturday, regardless of the interface language.

In both month displays, each day shows its civil date at the top left and its Hebrew date at the top right.

Hebrew Month

Hebrew Month organizes the grid by the Hebrew month and mirrors it from right to left, with Sunday on the right and Saturday on the left. This direction also remains independent of the interface language.

Moving through the calendar

Use Today to return to the current date. The single arrows move by the kind of month currently displayed—Hebrew or civil. The double arrows likewise move by the kind of year currently displayed—a Hebrew year in Hebrew Month, a civil year in Civil Month. Click a day to select it; a greyed day from the next or previous month opens its own month.

Go to Year

The calendar button beside Today opens a direct year chooser. Enter a Hebrew or a civil year: the calendar moves to the selected date’s own day and month in that year. In a civil year without 29 February, 29 February becomes 28 February. In a Hebrew year, a date the year doesn’t have follows the same rules as an anniversary: 30 Cheshvan or 30 Kislev becomes the 1st of the next month, Adar I or Adar II becomes Adar in a common year, and Adar becomes Adar II in a leap year. The double arrows in Hebrew Month treat Adar the same way.

For a civil year before the common era, type it with a minus sign (−500) or add BCE (500 BCE); such years are shown with “BCE” after them. Kaluach goes back to 3760 BCE — Hebrew year 1 began in the autumn of 3761 BCE.

Language

The EN / עב control changes the interface and date language without changing the inherent direction of either month display. The toolbar itself keeps the same layout in both languages, so its controls never change places and the arrows always point the same way: ◀ to earlier dates, ▶ to later ones.
