Question: When did Atzerodt rent room 126?
About the article "Assassination of Abraham Lincoln", section "Atzerodt fails to attack Andrew Johnson".

Candidate passages:
Booth had assigned George Atzerodt to kill Vice President Andrew Johnson, who was staying at the Kirkwood House in Washington.
Atzerodt was to go to the Vice President's room at 10:15 p.m. and shoot him.
On April 14, Atzerodt rented room 126 at the Kirkwood, directly above the room where Johnson was staying.
He arrived at the Kirkwood at the appointed time and went to the bar downstairs, carrying on his person a gun and a knife.
Atzerodt asked the bartender, Michael Henry, about the Vice President's character and behavior.
After spending some time at the hotel saloon, Atzerodt got drunk and wandered away through the streets of Washington.
Nervous, he tossed his knife away in the street.
He made his way to the Pennsylvania House Hotel by 2 a.m., where he checked into a room and went to sleep.
Earlier that day, Booth stopped by the Kirkwood House and left a note for Johnson that read, "I don't wish to disturb you.
Are you at home?
J. Wilkes Booth."
The card was picked up that night by Johnson's personal secretary, William Browning.
This message has been interpreted in many different ways throughout the years.
One theory is that Booth, being afraid that Atzerodt would not succeed in killing Johnson, or worried that Atzerodt would not have the courage to carry out the assassination, tried to use the message to implicate Johnson in the conspiracy.
Another theory is that Booth was actually trying to contact Browning in order to find out whether or not Johnson was expected to be at the Kirkwood that night.
In January 1865—some years after opening his failed carriage repair business—Atzerodt was introduced to John Wilkes Booth in Washington, D.C. by John Surratt.
Atzerodt was willing to join in Booth's earlier conspiracy to kidnap President Abraham Lincoln, as he later admitted in his trial, which began May 1, 1865.
According to the prosecution, Booth assigned Atzerodt to assassinate Vice President Andrew Johnson on April 14, 1865.
On that morning, Atzerodt booked room 126 at the Kirkwood House in Washington, where Johnson was staying.
However, he could not muster the courage to kill Johnson, so he began drinking at the hotel bar.
He presumably got drunk, and spent the night walking the streets of Washington.
During his stay at the hotel, Atzerodt had asked the bartender about Johnson's whereabouts.
This aroused suspicion the next day, after Lincoln was assassinated.
An employee of the hotel contacted the police regarding a "suspicious looking man in a gray coat.
"The military police then conducted a search of Atzerodt's room on April 15 and found that he had not slept in it the night before.
Additionally, he had a loaded revolver concealed under his pillow, as well as a concealed Bowie knife.
The police also found a bank book belonging to Booth in the room.
Atzerodt was arrested on April 20.
He was apprehended at the house of his cousin, Hartman Richter, in Germantown, Maryland. 
Atzerodt's attorney, Captain William Doster, stated to the court that he intended "to show that George Atzerodt was a constitutional coward; that if he had been assigned the duty of assassinating the Vice President, he could never have done it; and that, from his known cowardice, Booth probably did not assign to him any such duty."
However, this was to no avail.
After the conviction Atzerodt offered a confession to Reverend Butler, a minister who came to his cell to offer him comfort.
Butler said that Atzerodt admitted that he did in fact go to the meeting in March to help plan the kidnapping of President Lincoln while he attended a play at a hospital.
Atzerodt said he first heard about Booth's plan to assassinate the President just two hours before the shooting.
Atzerodt said that Booth really wanted David Herold to assassinate Vice President Johnson because he thought that Herold had "more pluck" than Atzerodt did.
Atzerodt said Booth wanted him to "back up" Herold and "give him more courage.
"Atzerodt and three other convicted conspirators (Mary Surratt, Lewis Powell, and David Herold) were hanged in Washington, D.C., on July 7, 1865.
Atzerodt's last words were: "May we all meet in the other world.
God take me now."
He did not die instantly; his neck did not break upon impact, and his body shuddered for several minutes before dying.
Atzerodt is interred under the fictitious name Gottlieb Taubert in St. Paul's Lutheran Cemetery in Baltimore, Maryland. 
George Andreas Atzerodt (June 12, 1835 – July 7, 1865) was a conspirator, with John Wilkes Booth, in the assassination of Abraham Lincoln.
Assigned to assassinate Vice-President Andrew Johnson, he lost his nerve and did not make an attempt.
He was executed along with three other conspirators by hanging. 
The Rents Act (Maximum Fair Rent) Order 1999 was introduced in Statutory Instrument 1999 No.
6 and came into force on 1 February 1999.
The Rent Officer continued to determine a fair rent as previously but was then required to calculate by a formula the maximum rent payable if this was lower than the fair rent.
The formula required a comparison between the retail price index at the date of the previous registration and the retail price index for the month immediately preceding the new determination of a fair rent.
There was an addition of 0.075 for the first registration after this new order came into force and 0.05 for every subsequent registration.
Variable service charges were not included in the calculation of the formula.
The Maximum Fair Rent did not apply where there had been a change in the condition of the dwelling house of the common parts as a result of repairs or improvements carried out by the landlord if the new rent determined as a result of these repairs or improvements exceeded the previous registered rent by at least 15%.
The Maximum Fair Rent was to be recalculated if the rent registered by the Rent Officer upon an application made on or after 1 February 1999, was referred to a Rent Assessment Committee.
Retail Prices Index used by Rent Officers and Rent Assessment committees is the monthly United Kingdom Index of Retail Prices (for all items), which is available from the Office for National Statistics or online.
The Rent Officer Service through the Institute of Rent Officers had been consulted in the past about legislative changes and procedures.
Suggestions were made through annual reports most of which were eventually incorporated into legislation.
One such recommendation was the creation of a nation service either as an executive agency or as a Non Departmental Public Body (NDPB).
The Rent Officer Service was established as The Rent Service as an executive agency of the Department of the Environment, Transport and the Regions on 1 October 1999.
Significant opportunities for service improvements were able to be made in line with the government’s modernising objectives.
The Rent Service became a single, national service with local delivery, building on existing experience to secure better performance and improved customer service.
The new organisation focused on faster processing of cases and consistency in valuation practice and decision making.
New information technology systems were introduced and greater openness and accountability was promoted whilst maintaining impartiality in valuations.
As no new protected tenancies had been created after 15 January 1989 after the Housing Act 1988 fewer applications for fair rents were received in most areas of the country except in central London.
There had however been a substantial increase in housing benefit valuations, and on 1 April 2004 The Rent Service was transferred to the Department for Work and Pensions DWP), which was the government department responsible for housing benefit legislation.
A major change to the valuation process for housing benefit was the Local Housing Allowance (LHA) a flat rate allowance paid to housing benefit claimants, which was introduced on 7 April 2008 as part of the welfare reform programme.
It applies to private sector tenants who make a new claim for housing benefit or those claiming housing benefit who change address.
It will also apply to tenants claiming housing benefit who move from the social sector into private sector accommodation.
LHA is a standard allowance based on the number of bedrooms: shared room (room in a shared property); one bedroom, two bedrooms, three bedrooms, four bedrooms and five bedrooms, in an area known as a Broad Rental Market Area (BRMA).
It is the median rent of private sector lettings for that size of accommodation in the BRMA.
The BRMA is a geographical area where a person could reasonably be expected to live, taking into account access to facilities and services for the purpose of health, education, recreation, personal banking and shopping.
The distance of travel to and from those facilities by public and private transport is taken into account and local authorities are consulted when BRMA are reviewed.
BRMA boundaries do not have to match the boundaries of a local authority and often fall across more than one local authority area.
The key to the success of this LHA is the regular review of the BRMA across England by the Rent Officer and the extensive development of lettings information now held by The Rent Service.
BRMA decisions and LHA levels are published monthly on a new web portal.
The published data includes full details and rationales for the BRMA and the list of rents gathered for each property size in that BRMA.
On 1 April 2009 the residual function of The Rent Service were transferred to become a part of the Valuation Office Agency.
Changes to the local housing allowance were announced in the June 2010 budget.
The first changes are planned to come into effect between April 2011 and October 2011.
The VOA Rent Officers now provide the BRMA and lettings data on a new facility for London.
