Introduction

The Six Millennium Catalog of Solar Eclipses is organized into a series of sixty 100-year web pages, each one covering a century of solar eclipses. The 100-year table below covers the period -2499 to -2400 (2500 BCE to 2401 BCE) [1]. The date and time of each eclipse is given for the instant of Greatest Eclipse. Each eclipse date links to a web page containing additional details and a map showing the geographic region of eclipse visibility for that eclipse. A description of each parameter in the catalog table can be found in Key to Catalog of Solar Eclipses.

For an explanation of how eclipses are classified, see Solar Eclipse Basics. The frequency of each eclipse type, the extremes in eclipse magnitude and duration, and other data for the century are presented in the Eclipse Statistics tables following the Catalog of Solar Eclipses. To select a different century, visit the Index to Six Millennium Catalog of Solar Eclipses.

Statistics for Solar Eclipses: -2499 to -2400 (2500 BCE to 2401 BCE)

During the 25th century BCE [2], Earth experienced 256 solar eclipses. The following table lists the number of eclipses of each type over this period.

Solar Eclipses: -2499 to -2400
Eclipse Type	Symbol	Number	Percent
All Eclipses	-	256	100.0%
Partial	P	95	37.1%
Annular	A	88	34.4%
Total	T	66	25.8%
Hybrid	H	7	2.7%

Annular and total eclipses can be classified as either central or non-central as follows: 1) Central (two limits), 2) Central (one limit) or 3) Non-Central (one limit). The statistical distribution of these classes during the 25th century BCE appears in the following three tables (no Hybrids are included since all are central with two limits).

Annular and Total Eclipses
Classification	Number	Percent
All	154	100.0%
Central (two limits)	152	98.7%
Central (one limit)	0	0.0%
Non-Central (one limit)	2	1.3%

Annular Eclipses
Classification	Number	Percent
All Annular Eclipses	88	100.0%
Central (two limits)	87	98.9%
Central (one limit)	0	0.0%
Non-Central (one limit)	1	1.1%

Total Eclipses
Classification	Number	Percent
All Total Eclipses	66	100.0%
Central (two limits)	65	98.5%
Central (one limit)	0	0.0%
Non-Central (one limit)	1	1.5%

There are a minimum of two and a maximum of five solar eclipses in every calendar year. Statistics for the number of eclipses each year during the century are listed below.

Number of Eclipses Per Year: -2499 to -2400
Number of Eclipses Per Year	Number of Years
2	63
3	19
4	17
5	1

The years containing five solar eclipses are as follows: -2438.

There are two solar eclipses in the same same calendar month as follows: -2478 Mar.

The longest and shortest central eclipses of the century as well as largest and smallest partial eclipses appear in the following table.

Extreme Durations and Magnitudes of Eclipses: -2499 to -2400
Extrema Type	Date	Duration	Magnitude
Longest Annular Solar Eclipse	-2408 Nov 28	09m13s	-
Shortest Annular Solar Eclipse	-2412 Aug 16	00m22s	-
Longest Total Solar Eclipse	-2407 May 24	06m20s	-
Shortest Total Solar Eclipse	-2453 May 22	01m36s	-
Longest Hybrid Solar Eclipse	-2411 Feb 08	01m35s	-
Shortest Hybrid Solar Eclipse	-2447 Jan 18	00m14s	-
Largest Partial Solar Eclipse	-2481 May 02	-	0.93661
Smallest Partial Solar Eclipse	-2467 Feb 28	-	0.01341

During the century, 5 Saros series begin and 3 Saros series end. The table below gives the Saros series, number of eclipses in the series, the calendar date and whether it is the first or last eclipse in the series.

Begin and End of Saros Series: -2499 to -2400
Saros Series	Number of Eclipses	Date	First/Last
11	76	-2492 Jan 06	First
-30	73	-2471 Apr 12	Last
10	73	-2467 Feb 28	First
16	85	-2456 Jul 23	First
17	74	-2427 Jul 03	First
-29	74	-2424 Apr 03	Last

Index to Six Millennium Catolog of Solar Eclipses

The links in the following table each open a web page containing a 100-year Catalog of Solar Eclipses. Each line in a 100-year catalog lists the primary characteristics for a single eclipse; the eclipse date itself links to a web page containing further details and a map showing the geographic region of eclipse visibility.

Calendar

The Gregorian calendar (also called the Western calendar) is internationally the most widely used civil calendar. It is named for Pope Gregory XIII, who introduced it in 1582. On this website, the Gregorian calendar is used for all calendar dates from 1582 Oct 15 onwards. Before that date, the Julian calendar is used. For more information on this topic, see Calendar Dates.

The Julian calendar does not include the year 0. Thus the year 1 BCE is followed by the year 1 CE (See: BCE/CE Dating Conventions). This is awkward for arithmetic calculations. Years in this catalog are numbered astronomically and include the year 0. Historians should note there is a difference of one year between astronomical dates and BCE dates. Thus, the astronomical year 0 corresponds to 1 BCE, and astronomical year -1 corresponds to 2 BCE, etc..

Eclipse Predictions

The eclipse predictions presented here were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates have been calculated with respect to the Moon's Center of Mass.

The largest uncertainty in the eclipse predictions is caused by fluctuations in Earth's rotation due primarily to tidal friction of the Moon. The resultant drift in apparent clock time is expressed as ΔT and is determined as follows:

1. pre-1950's: ΔT calculated from empirical fits to historical records derived by Morrison and Stephenson (2004)
2. 1955-present: ΔT obtained from published observations
3. future: ΔT is extrapolated from current values weighted by the long term trend from tidal effects

A series of polynomial expressions have been derived to simplify the evaluation of ΔT for any time from -2999 to +3000. The uncertainty in ΔT over this period can be estimated from scatter in the measurements.
