days a week in school for kindergarten/reception?

[Anonymous]

I teach junior and senior kindergarten in Ontario, Canada. The juniors are 3/4 and the seniors 4/5. My children are only in school two days a week with alternating Fridays. ie JK Mondays and Wed and SK Tues and Thurs and they alternate Fridays. How long are the children in England in school during the week? And what age do they start? Thanks!

Not being a parent, I'll have to go and ask one.
