Calendar View

Purpose

Calendar View serves many different purposes, all of which may be useful to support historical research:

It allows the easy identification of all days to which Hirtius event-like objects have been linked, colour-coded on a full year calendar by the types of events (clicking on any such day will display all linked events, split by type). See below for the list of objects that are considered event-like in this context.
It provides a perpetual calendar that can be used to display a full year calendar for any year in any of the supported eras (see Supported Eras) between 4713 BCE/ACN and 2499 CE/PCN. The display will also include the ISO week number.
It shows a full year calendar using the classical Roman day numbering (for any year in the same range as above) with the usual day numbering shown beside it for easy conversion.
It can also display the unconventional calendar that was used during those transition years between the Julian and Gregorian eras (a fixed list of known transition dates is provided by the program -- it is not exhaustive, but can be easily expanded if needed).

Supported event types

These are the Hirtius objects that will be identified by the Calendar View:

Slides (based on the 'shot_date' field)
Events (based on the 'date_start' field) -- this of course also applies to so-called "auto-events", namely those identifying the birth and death dates of Individuals, as well as the couple creation event for Families
Titles (based on the 'as_of' field)

In the case of Events and Titles, thanks to the internal representation of the associated date as a Julian Day Number, the objects will be returned for the correct date, no matter what era (Julian or Gregorian) they were encoded as, or what era is being queried through Calendar View.

Getting There...

There are two ways to reach this page: from the view page of any date-bearing object or through the application's Timeline Search menu.

From the view pages for Slides, Events, Individuals, Families or Titles, click on the small calendar icon next to the date field (), keeping in mind that this icon is only shown when a date is set. This will get you straight to the Calendar View page which will display the calendar for the year and era the event you started from was assigned to.

Alternatively, you can reach it by navigating the application's menus:

From the Main Application Menu (or indeed almost any other Project Hirtius page), click on the "Search" icon in the header (). This gets you to the Basic and Timeline Search Page in "basic" or "full text search" mode.
Click on the Timeline link in the navigation bar just below the page header. This gets you to the Basic and Timeline Search Page in "timeline search modality selection" mode.
Select "Calendar View" option in the Timeline search modality drop-down, then click Next to reach the Calendar View page.

When accessed in this way, the Calendar View page will display the calendar for the current year by default. Use the provided controls (see below) to request another one.

Controls

Navigation bar: At the top of the page, just below the header, you'll find links that you can use to switch between the four main search modes: Basic, Timeline, Advanced and Calendar Tools. This control acts like a set of "Tabs", where the currently active one is rendered as plain text, and other available choices are rendered as bold-face font links. On sub-pages (such as the "Timeline modality choice" or the "Search Result" page), the "current" tab will be rendered in regular font and link back to the previous step (the query term entry form, for instance). The last two choices are handled by separate pages and covered in Advanced Search Page and Calendar Tools}.
Year field: Specify the year for which the calendar should be drawn. Years are supposed to be entered as positive integer values (and the Sign drop-down -- see below -- used to select ACN/BC or PCN/CE), but negative values will be accepted and automatically converted to ACN years. Beware: there is no year '0'.
Sign drop-down: Select between ACN/BC and PCN/CE.
Era drop-down: Select between Julian, Gregorian and Transitional era (please refer to Supported Eras for an exact definition). The Transition selector is disabled when either "Julian" or "Gregorian" are selected. The Year and Sign fields are disabled when "Transitional" is selected.
Transition drop-down: Select the Julian to Gregorian transition to display from the list of supported ones. The list is shown in chronological order and mentions the geographical zone or area of political influence where it applied, as well as the year. For a complete list of supported transitions with all details, please refer to Supported Eras.
Display Roman dates radio button: Specify whether the current day numbering system should be used or the Roman one. If Roman is selected, the current day numbering will be shown in superscript next to the Roman numerals, to ease the conversion between the two systems.
Go button: Submits the HTML form fields contents to be used and displays the requested calendar.
Day links: Each day in the selected year calendar that has linked event-like objects will be identified by a coloured background and its number being rendered as a link. The background colour is a code that reprensents the type of objects linked to that day (the key is located below the calendar table). Hovering the mouse on the link shows the short name of those linked objets. Clicking on the link leads to the Calendar Search Result Page, where matching objects of all types will be listed in full details.
