Python | Pandas tseries.offsets.CustomBusinessHour.rollforward

| |

DateOffsets can be created to move dates by a specified number of valid dates. For example, Bday (2) can be added to a date to move it two business days forward. If the date does not start with a valid date, it is first moved to a valid date and then an offset is generated.

tseries.offsets.CustomBusinessHour.rollforward() Pandas tseries.offsets.CustomBusinessHour.rollforward() is used to scroll the provided date forward to the next offset, only if not offset.

Syntax: pandas.tseries.offsets.CustomBusinessHour.rollforward (dt)

Parameter:

dt: date

Returns: rollforward

Example # 1: Use pandas.tseries. offsets.CustomBusinessHour.rollforward () to flip the supplied date forward if not offset.

Output:

Now we will add an offset to this timestamp object to increase datetime value. We will also check if the given date is shifted or not. If not, then we will move this date to the next offset.

# import pandas as pd

 import pandas as pd

 
# Create a timestamp

ts = pd.Timestamp ( ’2019-4-23 11: 15: 00’ )

 
# Create offset

cbh = pd.tseries.offsets.CustomBusinessHour (n = 2 , weekmask = ’Mon Tue Wed Thu’ ,

  start = ’12:00’ )

 < / code> 
# Print time stamp

print (ts)

 
# Print offset

print (cbh)

# Adds an offset to the specified timestamp

new_timestamp = ts + cbh

 
# Print updated timestamp

print (new_timestamp)

 
# roll forward if not offset

result = cbh.rollforward (pd.Timestamp ( ’2019-4-28 11 : 15: 00’ ))

 < br /> # print the result

print (result)

Output:

As we can see in the output, we have successfully created an offset and added it to the given timestamp. We’ve also pushed the date forward to the next offset.

Example # 2: Use pandas.tseries.offsets.CustomBusinessHour.rollforward () to scroll through the provided date forward if not offset.

# import pandas as pd

import pandas as pd

 
# Create a timestamp

ts = pd.Timestamp ( ’2019-4-23 11: 15: 00’ )

 
# Create offset

cbh = pd.tseries.offsets.CustomBusinessHour (st art = ’07: 00’ , end = ’14:00’ )

 
# Print time stamp

print (ts)

 
# Print offset

print (cbh)

Output:

Now we will add an offset to the given timestamp object to increment the datetime value. We will also check if the given date is shifted or not. If not, then we will move this date to the next offset.

# Adds an offset to the specified timestamp

new_timestamp = ts + cbh

 
# Print updated timestamp

print (new_timestamp)

 
# roll forward if not offset

result = cbh.rollforward (pd.Timestamp ( ’2019-4-28 11 : 15: 00’ ))

 < br /> # print the result

print (result)

Output:

As we can see in the output, we have successfully created an offset and added it to the given timestamp. We’ve also moved the date forward to the next offset.
