Aindram Vedic Calendar

Under the date your theme already shows on a post or page, Aindram Vedic Calendar adds a second line with the same day in the Vedic calendar:

November 3, 2026
Tula 17, KaliYuga 5127

• Months are Kerala’s solar months, named by their signs in Sanskrit: Mesha, Vrishabha, Mithuna, Karkataka, Simha, Kanya, Tula, Vrishchika, Dhanu, Makara, Kumbha, Meena. Mesha is the month Kerala calls Medam, Simha is Chingam, and so on.
• Years are KaliYuga years. The year begins at Vishu, the first day of Mesha. The year that began at Vishu in April 2026 is KaliYuga 5127.

It works with block themes and classic themes, with no setup. Choose the post types and the wording in Settings > Aindram Vedic Calendar. You can also link the date to this plugin’s page, so a reader who wonders what it is can find out; that is off unless you turn it on.

How the date is reckoned

A solar month begins when the Sun enters a sidereal sign, its sankranti. The plugin computes the Sun’s position with the VSOP87 planetary theory and the Lahiri (Chitrapaksha) ayanamsa, the standard of the Indian national ephemeris.

Kerala’s rule then fixes the first day of the month. The daytime, sunrise to sunset, is divided into five parts. If the sankranti falls within the first three, the month begins that day; otherwise it begins the next day. Sunrise and sunset are taken at Thiruvananthapuram.

Accuracy

Every month start from 1900 to 2600, 8,409 of them, was checked against Swiss Ephemeris with the same rule: all fall on the same day. Sankranti times agree within 4 seconds, and the first-day cut-off within half a second. The month starts also match the Malayalam calendar Kerala Tourism publishes for 2024-25.

Dates centuries ahead depend on how much the Earth’s rotation will have slowed, which nobody can know. The plugin uses the same forecast as Swiss Ephemeris, so its future dates agree with almanacs built on it.

Almanacs that use a different ayanamsa or their own reckoning of sunrise can differ by a day when a sankranti falls within minutes of the cut-off.

Privacy

The plugin sends nothing anywhere and stores nothing but its two settings. The dates are worked out on your server.
