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 -2099 to -2000 (2100 BCE to 2001 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: -2099 to -2000 (2100 BCE to 2001 BCE)

During the 21st century BCE [2], Earth experienced 225 solar eclipses. The following table lists the number of eclipses of each type over this period.

Solar Eclipses: -2099 to -2000
Eclipse Type	Symbol	Number	Percent
All Eclipses	-	225	100.0%
Partial	P	80	35.6%
Annular	A	67	29.8%
Total	T	69	30.7%
Hybrid	H	9	4.0%

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 21st 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	136	100.0%
Central (two limits)	130	95.6%
Central (one limit)	3	2.2%
Non-Central (one limit)	3	2.2%

Annular Eclipses
Classification	Number	Percent
All Annular Eclipses	67	100.0%
Central (two limits)	64	95.5%
Central (one limit)	1	1.5%
Non-Central (one limit)	2	3.0%

Total Eclipses
Classification	Number	Percent
All Total Eclipses	69	100.0%
Central (two limits)	66	95.7%
Central (one limit)	2	2.9%
Non-Central (one limit)	1	1.4%

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: -2099 to -2000
Number of Eclipses Per Year	Number of Years
2	77
3	21
4	2
5	0

There are two solar eclipses in the same same calendar month as follows: -2044 May, -2033 Apr.

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: -2099 to -2000
Extrema Type	Date	Duration	Magnitude
Longest Annular Solar Eclipse	-2000 Dec 16	11m36s	-
Shortest Annular Solar Eclipse	-2025 Oct 25	00m07s	-
Longest Total Solar Eclipse	-2017 Jun 01	06m40s	-
Shortest Total Solar Eclipse	-2048 Feb 16	00m37s	-
Longest Hybrid Solar Eclipse	-2093 Jan 05	01m36s	-
Shortest Hybrid Solar Eclipse	-2082 May 30	00m02s	-
Largest Partial Solar Eclipse	-2029 Jan 17	-	0.99375
Smallest Partial Solar Eclipse	-2051 Oct 12	-	0.01770

During the century, 3 Saros series begin and 2 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: -2099 to -2000
Saros Series	Number of Eclipses	Date	First/Last
-15	72	-2073 May 21	Last
30	83	-2051 Oct 12	First
25	71	-2033 Apr 30	First
-14	72	-2008 May 22	Last
26	72	-2004 Apr 08	First

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.
